Exploring snippets won't display project-scoped snippets
<!--This issue template can be used as a great starting point for feature requests. Learn more about the process: https://handbook.gitlab.com/handbook/product/how-to-engage/#customer-feature-requests. The section "Release notes" can be used as a summary of the feature and is also required if you want to have your release post blog MR auto generated using the release post item generator: https://about.gitlab.com/handbook/marketing/blog/release-posts/#release-post-item-generator. The remaining sections are the backbone for every feature in GitLab. The goal of this template is brevity for quick/smaller iterations. For a more thorough list of considerations for larger features or feature sets, you can leverage the detailed [feature proposal](https://gitlab.com/gitlab-org/gitlab/-/blob/master/.gitlab/issue_templates/Feature%20proposal%20-%20detailed.md).--> ### Release notes <!--What is the problem and solution you're proposing? This content sets the overall vision for the feature and serves as the release notes that will populate in various places, including the [release post blog](https://about.gitlab.com/releases/categories/releases/) and [Gitlab project releases](https://gitlab.com/gitlab-org/gitlab/-/releases). "--> Project-scoped snippets appear in the snippet exploring view. ### Problem to solve <!--What is the user problem you are trying to solve with this issue?--> In an on-premise installation where there are a few projects and shareable snippets are scattered across them, there's no easy way to explore them all. Even if you store project-related snippets in projects within a group or subgroup, there's no way to browse all snippets for the group. ### Proposal <!--Use this section to explain the feature and how it will work. It can be helpful to add technical details, design proposals, and links to related epics or issues.--> Include project-scoped snippets when browsing the `/explore/snippet` controller. ### Intended users * [Priyanka (Platform Engineer)](https://handbook.gitlab.com/handbook/product/personas/#priyanka-platform-engineer) * [Sidney (Systems Administrator)](https://handbook.gitlab.com/handbook/product/personas/#sidney-systems-administrator) * [Dana (Data Analyst)](https://handbook.gitlab.com/handbook/product/personas/#dana-data-analyst) ### Feature Usage Metrics <!--How are you going to track usage of this feature? Think about user behavior and their interaction with the product. What indicates someone is getting value from it? Explore (../../doc/development/internal_analytics/internal_event_instrumentation/quick_start.md) for a guide.--> This adds more info on an existing controller, or adds a new controller (depending on how it gets implemented). If it is useful, the usage statistics of that controller should raise. ### Does this feature require an audit event? <!--- Checkout these docs to know more https://docs.gitlab.com/ee/development/audit_event_guide/#what-are-audit-events https://docs.gitlab.com/ee/administration/audit_events.html ---> <!--Label reminders Make sure to add the appropriate labels for the product stage and/or group (e.g ~"devops::plan") if known and add a comment tagging the appropriate Product Manager. Use the following resources to find the appropriate labels: - Use only one tier label choosing the lowest tier this is intended for - https://gitlab.com/gitlab-org/gitlab/-/labels - https://about.gitlab.com/handbook/product/categories/features/ Examples: /label ~group:: ~section:: ~Category: /label ~"GitLab Free" ~"GitLab Premium" ~"GitLab Ultimate"-->
