Description:

• Add validation to the git create branch, ensuring that project branch conventions are kept.
• Make the whitespace char - configurable (we default space etc. to underscore - meaning we cannot just past in issue title and be done)

Example implementation:

I can create an initial pr. with the implementation for further discussion, if this is something the vscode team would consider.

eg. if the change should enable extensions to lint/validate the branch name or be a configuration etc.

Kind regards Morten
