[FEAT]: Ref methods should support full names with or without the refs/prefix

[tmobaird]

Describe the need

The create_ref method supports refnames with or without the refs/ prefix. This is a really nice quality of life feature for consistency. The following ref methods do not include this:

• ref
• update_ref
• delete_ref

It would be great to add this support for these methods as well.
