[Feature Request] `az repos show` should auto-detect `--repository` via git config

az repos show

Is your feature request related to a problem? Please describe.

I work across many repos, and it's often useful to jump to the Azure DevOps repo that corresponds to a locally cloned repository.

It would be nice if I could run az repos show --open and have the CLI automatically detect the repository from the git config, as it does for --org and --project. Instead, I have to pass the repository name explicitly via the --repository parameter.

Describe the solution you'd like

I would like for --repository to be auto-detected when inside a git repo, as it already is for --organization and --project.

Describe alternatives you've considered

Currently I have a cumbersome PowerShell workaround like this:

az repos show --open --repository "$(((git config --get remote.origin.url) -split '_git/')[-1])"

I've never contributed to the repo before, but following the dev setup guide I was able to get a local version of the extension running, and it appears that a change like this should be sufficient:
