feat: add focus event option for the checklist extension

[rayterion]

Description

This PR adds an optional configuration parameter, disableTakeFocusOnClick, to CheckListExtension. This allows users to enable or disable editor focus when clicking on checklist items, as described in the related issue:

• Closes Feature: Add an option to disable focus on click in CheckListPlugin #7689

The changes are implemented in a way that does not break existing usages of CheckListExtension or the CheckListPlugin React component. The new parameter is optional and defaults to the current behavior.

Note: In the file LexicalCheckListPlugin.js.flow, I added what I believe is the correct change based on patterns observed in similar files. However, I did not deeply verify the purpose of all files in that directory, so this part should be reviewed.

Test plan

I tested the behavior by running pnpm run start and verifying how checklist items behave when clicked, both with and without the disableTakeFocusOnClick option enabled.
Steps:

1. Open packages/lexical-playground/src/appSettings.ts and set shouldDisableFocusOnClickChecklist to either false or true (default is false)
2. run pnpm run start
3. create a checklist in the editor (shortcut Ctrl+Shift+9 on pc).
4. Verify the focus behavior

I have not yet explicitly tested whether the mobile keyboard correctly dismisses when the option is set to true. However, in theory, this should work as expected, since the keyboard should only appear when the editor receives focus.

Additional Context

I noticed there is an existing open PR with the same goal as this one, but it was not completed by its author. For reference:

• feat(list): add disableTakeFocusOnClick option to CheckListPlugin (#7689) #7696

It would be good to add some tests for this feature, right now there's nothing that demonstrates that it works

This feature still doesn't have any tests, when you add some I will take another look

I've added the test file. I took a little longer because i was trying to understand the standards for testing in Lexical, but i think i got it right.

In this case since we're dealing with focus, etc. and you're using mocks to change the environment's behavior it seems like a better approach would be to write an e2e test for this feature that uses a real browser. Mocking here makes it seem like maybe the tests aren't really doing anything meaningful.

E2E tests added. Tackling those conflicts now.
