Fix CLI argument parsing collision

[edabor]

The server CLI arguments can collide with user and/or libraries argument parser.
Especially, the ipykernel package CLI has a --f arguments that collides with the server's --follow-symlinks and --fs-endpoints.
See pyvista/pyvista#8040 and pyvista/pyvista#8044

This PR patches the issue by disallowing abbreviations.

This can be considered as a incomplete fix, since users can still have their custom CLI parser implementing one of server's argument (ie. --follow-symlinks by mistake) and unexpectedly pass arguments to server CLI parser.
Maybe we could mitigate that by including in the trame documentation that when using a custom argument parser, it is recommended to pass arguments via the --trame-args argument or with the TRAME_ARGS env variable.
