When job is created from the notebook top panel, input path with "RTC:" still breaks functionality

[andrii-i]

Description

• Accordingly to issue Input Path with Prefix "RTC:" breaking functionality #429 "when both jupyter-collaboration and jupyter_scheduler extensions are installed, jupyter_scheduler will detect notebook.ipynb as RTC:notebook.ipynb which causes jupyter_scheduler failing to find the file in path"
• PR Support jupyter-collaboration by handling RTC prefix in the file paths #541 fixes this issue but only when job is created from the file browser, not from the notebook top panel
• While JupyterLab 4.4.0a2 (will be released as a non-preview 4.4) adds Content Provider API that removes the RTC prefix problem completely (PR 17092), we should still have this behavior fixed in Jupyter Scheduler for all scenarios for the sake of support of JupyterLab < 4.4.

How to reproduce

1. Install both Jupyter Scheduler and jupyter-collaboration
2. Try to create a new job from the notebook top panel (not from the file browser)

Proposed Solution

Use getLocalPath function added in #541 on the filepath when job is created from the notebook top panel to check for the presence of RTC prefix and remove it.
