fix: pre-commit warning

[bryghtlabs-richard]

Description

Resolve this warning:

[WARNING] hook id commitizen-branch uses deprecated stage names (push) which will be removed in a future version.
run: pre-commit migrate-config to automatically fix this.

Also include the motivation (why this change) and context.

1. Not to have warnings on each commit.
2. Follow the Commitizen preferences to rename push to pre-push.
