(PTFE-3058) Add support for copilot branch

[matthiasL-scality]

This pull request expands support for automated branch types in the workflow and test suite by introducing copilot and claude as recognized branch prefixes. It also updates tests and configuration to ensure these branches are handled correctly, particularly in scenarios where Jira ticket checks can be bypassed.

Branch prefix support:

• Added copilot and claude to the list of recognized prefixes in the FeatureBranch class, allowing these branches to be processed like other automated branches.
• Updated the settings.sample.yml configuration to document and accept copilot and claude as valid bypass prefixes for issue tracker checks.

Test coverage improvements:

• Added test cases in test_feature_branch_names to verify that copilot and claude branches do not require Jira issue keys or projects.
• Expanded the test_not_my_job_cases to include copilot and claude branches, ensuring they are handled appropriately in scenarios where jobs are not assigned.
• Introduced new tests for copilot and claude pull requests in test_dependabot_pr, confirming that these PRs can bypass Jira ticket requirements when properly configured.
