Follow-up from "Remove "Try now" CTA from code suggestions non owner alert"

The following discussion from !139787 (merged) should be addressed:

• @aqualls started a discussion: (+2 comments)

  I would LOVE to fix this grammar while we're here, because the comma's not right:

          = s_("CodeSuggestionsGAAlert|Quickly and securely author code by getting suggestions in your IDE while you type. Available in multiple languages. Try Code Suggestions today.")

• We also want to add a text link for your IDE and direct the user to our docs on supported web IDEs extensions: https://docs.gitlab.com/ee/user/project/repository/code_suggestions/index.html#supported-editor-extensions
