[LS] Introduce a minimum language server version application setting
<!--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/product-management/#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).

### Problem to solve
<!--What is the user problem you are trying to solve with this issue?-->
Instance administrators cannot set a minimum client version for connections from editor extensions.
### 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.-->
Provide instance administrators an option to specify the minimum language server version to connect to their instance.
### Intended users
<!--Who will use this feature? If known, include any of the following: types of users (e.g. Developer), personas, or specific company roles (e.g. Release Manager). It's okay to write "Unknown" and fill this field in later.
Personas are described at https://handbook.gitlab.com/handbook/product/personas/
* [Sidney (Systems Administrator)](https://handbook.gitlab.com/handbook/product/personas/#sidney-systems-administrator)

### 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.-->
Existing snowplow usage metrics provide insight into language server version used in code suggestions requests we could confirm the response status based on this and other track extension version metrics.
