Support jupyter-collaboration by handling RTC prefix in the file paths

• Fixes Input Path with Prefix "RTC:" breaking functionality #429
• JupyterLab reference PR fixing inability to create files in custom drives (everytime a file path is being handled, it should be assumed there can be a drive prefix in the file name) https://github.com/jupyterlab/jupyterlab/pull/15291/files#diff-a05e6e7e60f1adc4ea4f416f51df2d1e0277a12b5c84dea329859c9ccd6aef96R412-R427
• JupyterLab work in progress PR that would remove the need for special handling of drive prefixes (won't be in JupyterLab 4.3, JupyterLab 4.4 earliest) Service manager as plugin jupyterlab/jupyterlab#16556

Code changes

getSelectedFilePath helper function now uses serviceManager.contents API to check if there is an added “RTC” drive name in the file path and return local path without it.

User-facing changes

Jupyter Scheduler now works when jupyter-collaboration is installed.

Backwards-incompatible changes

None

Testing

Manually tested the following scenarios with jupyter-collaboration installed:

• Create a Job ✅
• Create a Job Definition (job with a schedule) ✅
• Create a job or a job definition with input folder included ✅
• Create a job from a notebook whose name starts with "RTC:" ✅

@andrii-i Can you also post a link to the JupyterLab PR that provided the getLocalPath() reference implementation as a comment on this PR?

[andrii-i]

@dlqqq thank you for looking into this. I added links to reference PRs into the PR description.

Tested the fix by adding the "RTC:" prefix manually too and it works great in all cases. Thanks @andrii-i !
