Remove panicbit.cargo extension warning

A warning was introduced regarding the incompatabilities between `rust-analyzer` and `panicbit.cargo`'s diagnostics / `cargo check` functionality.

This functionality has been removed in the latest version of the cargo extension (`0.3.0`), which is why the warning can be removed now.
