The Integrations Project Selector used to enable Slack, Jira, or other integrations should have a filter
Problem
When users are enabling the Slack integration, they need to select which project they want to add the integration to. The project dropdown does not have any filtering capability, making it difficult to find a project if you have a long list of projects to choose from. In it's current state, it may not only be a challenge to find your project, the list may hit a limit and not display your project at all - which blocks the user from completing the workflow.
The user enters the product selector page when they are setting up the Slack integration from outside of GitLab. For example, from the Slack app directory or the public facing about.gitlab.com
page (gitlab-com/marketing/digital-experience/buyer-experience#1281 (closed)).
