<!--This template is a great use for issues that are feature::additions or technical tasks for larger issues.-->
### Description
Currently, Merge Request branch workflow doesn't prevent creating an MR from unwanted branches to the target branch.
For example, I have the following:
\*\*Branch name pattern "\*\*develop/\*" redirect to **Target branch** "main"
**Branch name pattern** "feature/\*" redirect to **Target branch** "develop"
Then, as a Developer, I create an MR from feature-1, the MR defaults the target to "develop" branch, but I can easily change that target to "main" again.
### Proposal
Make this redirection enforced for certain roles.
<!--Use this section to explain the feature and how it will work. It can be helpful to add technical details, design proposals, and links to related epics or issues.-->
<!--Consider adding related issues and epics to this issue. You can also reference the Feature Proposal Template (https://gitlab.com/gitlab-org/gitlab/-/blob/master/.gitlab/issue_templates/Feature%20proposal%20-%20detailed.md) for additional details to consider adding to this issue. Additionally, as a data oriented organization, when your feature exits planning breakdown, consider adding the `What does success look like, and how can we measure that?` section.-->
