Docs feedback - feature proposal: Update tracking submodules to tip of branch

Problem to solve

Add a feature to update tracking submodules to tip of branch when running CI tasks.

I currently use a feature in Jenkins that will automatically checkout the tip of a specified branch of git submodules. (See documentation at https://github.com/jenkinsci/git-plugin/blob/git-4.2.0/README.adoc#advanced-sub-modules-behaviours) I would like this feature to be implemented in Gitlab.

Based on this Stackoverflow question, it appears that others would like this functionality too.

Intended users

Mainly these personas:

• Rachel (Release Manager)
• Devon (DevOps Engineer)

Proposal

I propose adding a new value for the git submodule variable (name TBD) that will cause the gitlab worker to use the --remote flag when updating submodules.

Documentation

Unknown

Availability & Testing

TBD

What does success look like, and how can we measure that?

TBD

What is the type of buyer?

This should go in the Free tier.
