Enable "--merge-prerelease" behavior in "cz bump" command #1934

Description

Currently, the --merge-prerelease option is only available in the cz changelog command, even though both changelog and bump respect the changelog_merge_prerelease = true setting.

It would be great to enable/disable changelog_merge_prerelease when calling cz bump in combination with update_changelog_on_bump = true/--changelog. This way, we could get incremental changelogs for every prerelease and a full changelog when bumping to a non-prerelease version.

Possible Solution

Add a --(changelog-)merge-prerelease flag to the cz bump command, mirroring the existing option in cz changelog, to override/set the changelog_merge_prerelease setting.
