Memory leak and crash in git bash if `--destination-path` is pefixed with a `/` for ` az storage file upload-batch`

### Describe the bug

When passing a path with a prefixed `/` to the `--source` flag In **git bash** (Used in Azure pipelines on windows agent) `az storage file upload-batch` stalls and consumes more and more ram until it runs out and crashes.

Screenshot from my machine after about 20 sek. of running:

This is the command that makes it crash:
`az storage file upload-batch --destination "$FILE_SHARE_URL" --source '.\Add-AppDevPackage.resources'/ --destination-path "/some/path" --account-key "$ACCOUNT_KEY" --debug`

This one works as expected:
`az storage file upload-batch --destination "$FILE_SHARE_URL" --source '.\Add-AppDevPackage.resources'/ --destination-path "some/path" --account-key "$ACCOUNT_KEY" --debug`

The subtle difference being that the second one does not have a `/` prefixed to `some/path`. I noticed in the debug output that git bash expanded `/some/path` into `C:/Program Files/Git/some/path`. This is probably out of scope for this repo, however, an error message about the path being invalid should be put in place instead of increasing memory consumption until it crashes.
