feat(usergroups): add missing team_id argument to usergroups.users.list

[maartenpaauw]

Why

Slack documents team_id as an optional argument for usergroups.users.list:

team_id (string) — The user group's encoded team ID. Required if org token is used.

It's missing from the patched OpenAPI spec, so the generated endpoint rejects it:

$client->usergroupsUsersList([
    'usergroup' => 'S0123',
    'team_id'   => 'T0123', // Symfony\Component\OptionsResolver\Exception\UndefinedOptionsException
]);

usergroups.list already carries this same override — this brings usergroups.users.list in line.

What

• Specification override — add the team_id query parameter to /usergroups.users.list in resources/slack-openapi-patched.json
• Refresh resources/slack-openapi-sorted.patch (new hunk + cascaded hunk offsets, same shape as Add team_id support for 3 endpoints #140)
• Regenerate the affected endpoint code (generated/Endpoint/UsergroupsUsersList.php, generated/Client.php docblock)
• Changelog entry

Verification

• The patch applies cleanly to slack-openapi-sorted.json and reproduces slack-openapi-patched.json exactly
• generated/ diff is limited to what a full Jane regen produces for this spec change
• JsonSorterTest passes (patched spec still correctly sorted)
• php-cs-fixer --dry-run clean

Note on check-spec

A full jane-openapi generate with the current latest Jane also rewrites a large number of unrelated Normalizer / BaseEndpoint files (Jane template drift since the last full rebuild in #189). That churn is intentionally not included here so this PR stays scoped to team_id. If check-spec fails on that unrelated diff, it reflects the pre-existing Jane-version drift on main rather than this change — happy to rebase once the SDK is rebuilt.

Hello, thank for you contribution, it looks good!

I just updated the SDK on main, can you rebase please?

[maartenpaauw]

@damienalexandre thanks for the quick response! I've rebased my branch and it is up-to-date with main.
