lints.workspace is not allowed to be false

[Kriskras99]

Summary

I expect to be able to set lints.workspace to false to explicitly opt out of the workspace lints.
Currently this is not allowed.

It would also be helpful for a potential lint like #11933.

Reproducer

I tried this code:

[lints]
workspace = false

I expected to see this happen:
No lints are imported from the workspace, and Clippy runs normally.

Instead, this happened:

error: `workspace` cannot be false
  --> Cargo.toml:18:13

18 | workspace = false
   |             ^^^^^

This would need to be brought up in the cargo issue tracker as cargo defines/parses the lints table
