Docs: Updates for Ruby support

[hubwriter]

This is a sister PR to Calum's PR #6860 which adds new articles for Ruby,
and a companion to this PR for the changes to the articles on docs.github.com.

This PR mentions Ruby in various existing articles.
See the 2nd half of the documentation plan (https://github.com/github/docs-content-strategy/blob/main/content-design-plans/docs-content/5017/plan.md#on-codeqlgithubcomdocs) for details of the changes.

NOTES

• I haven't added a "built-in support" table for Ruby on the "Supported languages and frameworks" (i.e. like this one for JavaScript. I mentioned this to @calumgrant and it sounds like we can leave this out for now.

@shati-patel:

• I haven't added a link to Ruby query help on this page https://codeql.github.com/codeql-query-help/, or the https://codeql.github.com/codeql-query-help/ruby/ page that contains the link to the individual query help pages, as I'm not sure how much of this is added/updated automatically.
• As above, I also haven't added a Ruby link to the "CodeQL CWE coverage" page https://codeql.github.com/codeql-query-help/codeql-cwe-coverage/. Does the CWE page for Ruby get automatically generated.

TODO: Once Calum's PR is merged EDIT: now done ✅
update
docs/codeql/codeql-language-guides/codeql-for-ruby.rstadding this line:
.. include:: ../reusables/ruby-beta-note.rst
Adding it to Calum's PR now won't work as the reusable is in my PR.

LGTM, Thanks!

I'll take a look along with my changes to the automation - if anything needs to be added manually, I'll make sure to do that!

@calumgrant What's the minimum Ruby version we support? What are the glibc requirements?

[calumgrant]

In terms of Ruby version, there is no minimum version.

For the public beta, there will be a minimum supported version of glibc - TBD. (I'm still investigating this).

The the GA, we hope to make this more robust by linking glibc statically. Tracked in https://github.com/github/codeql-team/issues/550

[calumgrant]

We require glibc 2.17

We require glibc 2.17

I'm not sure where this should be documented for Ruby. I can't find a similar requirement for other languages in the docs on https://codeql.github.com/docs/

@jf205 / @shati-patel - do you have a view on where to document this 👆?

We have a table of supported languages and compilers. Maybe there should be an entry for Ruby and glibc 2.17 there?

(The source file is https://github.com/github/codeql/blob/main/docs/codeql/support/reusables/versions-compilers.rst)

[turbo]

We should def add it, as it has been causing issues for customers in the private beta. We can flesh this out for other languages over time.

[hubwriter]

@shati-patel / @turbo - Thanks
I did wonder about that table, but it doesn't have a column for requirements (maybe it should?).

I think I'll add a footnote for Ruby.
Is this sufficient: "Requires glibc 2.17" ?
