Polish the enterprise enhanced context panel

[dominiccooney]

Changes to the enterprise enhanced context panel:

• Pluralizes repo/repos in the repo tree view summary line
• Updates counts in the repo tree view summary line
• Mentions the number of ignored repos in the repo tree view summary line (if any)
• Adds a help tooltip with a link to documentation
• Removes the help button from the right-hand side toolbar
• Clicking outside the repo picker popup accepts the edits instead of cancelling them
• Alt-tabbing while the repo picker popup is open does not dismiss it

Part of #1322

Test plan

Tested manually.

1. Run with CODY_JETBRAINS_FEATURES=cody.feature.internals-menu=true
2. Sign into an Enterprise account
3. Verify the repo picker is collapsed, one line and the edit pencil is visible
4. Hover the repo picker and verify the tooltip, opening the link goes to context documentation

5. Add repos and verify the summary line language updates, pluralization is correct, etc.
6. Use Internals, Testing: Cody Ignore and ignore some repositories, check the "ignored" language updates, etc.

7. Verify the details of adding repositories with the pencil:

   • Change text, press ESC, repo list should not update
   • Change text, press cmd-enter, repo list should update
   • Change text, click outside popup, repo list should update (new behavior)

8. Open the pencil popup, verify that cmd-tab/alt-tab away from IntelliJ and back does not close the popup

I just tried it on macOs. Things work ok according to your Test Plan.

I noticed this.

1. Hover on "Chat Context X Repos"
2. "About chat context" tooltip appears
3. Hover on a repository
4. Both "About chat context" and repository url (or info about included repo)

Is it ok that we present these two tooltips at once?

not for this PR but we may be able to get rid of TrialEndingSoonNotification

I tried it on windows too - works 🚀

@mkondratek yeah that's not ideal... @danielmarquespt wanted the tooltip to just trigger for the top row, actually. But that will take some work because the tree view items' tooltips are only text.

Another problem with this is the positioning gets in the way of the treeview expand/collapse disclosure arrow.

@toolmantim is working on a refresh of this UI, so this may not live long.

If it is still an issue after the refresh I'll work on custom triggering. It is cheesy but maybe we can watch the mouse movement and push the tooltip in and out of the tooltip properties when the mouse is in the "hot zone" on the top row. Needs investigation whether that will hide the tooltip once it is visible.
