Add gitFlowFinishArgs config option for git flow finish

[Xyerophyte]

Summary

• Adds a new gitFlowFinishArgs config option under git: that accepts a list of extra arguments to append to git flow <type> finish <name>
• When the list is empty (default), git flow finish behaves exactly as before
• Useful for teams that need flags like --keepremote or --keeplocal to control post-finish behavior

Closes #5296

Example config

git:
  gitFlowFinishArgs:
    - --keepremote

Changes

• pkg/config/user_config.go: Added GitFlowFinishArgs []string field to GitConfig with empty default
• pkg/commands/git_commands/flow.go: Appends configured args to the git flow finish command via the Arg() builder
• pkg/commands/git_commands/flow_test.go: Added test cases for single and multiple extra args
• schema-master/config.json: Added schema entry for the new field
• docs-master/Config.md: Added documentation for the new config option

Test plan

• Existing tests for git flow finish still pass (no args = same behavior)
• New test: single extra arg (--keepremote) is appended
• New test: multiple extra args (--keepremote --keeplocal) are appended
• CI validates auto-generated schema and docs match
