Add sub-command to update plugins version in profiles

[nicogodet]

Port this script https://gitlab.com/isl-ingenierie/qgis/isl_qgis_profiles/-/blob/main/scripts/update_plugins/update_plugins.py?ref_type=heads in QDT

Sub-command should take as argument a profile file to allow a better control (experimental, profile version bump, ...)

Before I start implementing this, I would like to discuss a bit about the design of this command.

Currently, the script linked just list all profiles in profiles folder and update the plugin versions.
I think it would be better to provide as input of the command, the path to the desired profile.json to process. it would allow a better control on exp/stable version for example.

Any thoughts ?
