Update client cursor pagination

[Ercogx]

Discussed it on #177

Changes:

• Updated CURSOR_PAGINATION constant.
• Added a docblock for the virtual method.
• Wrote tests to verify pagination methods.
• Removed Note: the virtual methods are not yet documented ... from the docs.

Hum the Check SDK is in sync with spec test is failing, but that's on us I think main is not up to date with the latest Jane updates.

The Check Coding Standards test can be fixed on your side by running PHP CS Fixer (make cs).

[damienalexandre]

I fixed main, so you case rebase, run make cs and push 👍

LGTM, thanks 🎉

There is a problem with the tests - testItCanUploadFile returns a deprected error. I can make another PR for this

[damienalexandre]

There is already a PR about the upload situation, if you want to jump in! :-) Thanks a lot for your contribution!

When we merge on "main" tests are run on a real Slack API and it looks like one method fail:

https://github.com/jolicode/slack-php-api/actions/runs/13564828905/job/37915496874

1) JoliCode\Slack\Tests\ClientTest::testAllCursorPaginationMethodExists
JoliCode\Slack\Exception\SlackErrorResponse: Slack returned error code "missing_scope"

The only added method is https://api.slack.com/methods/usergroups.list so we probably need to add usergroups:read to our token.

I will have a look later.

I think that the problem is this, here's a list of scopes for my test apps. I thought about CONTRIBUTING.md could be updated where to add describe the process to run the tests

Tests are green now I added the missing scope and updated the documentation.

Thanks a lot.
