Rollup merge of #87346 - rylev:rename-force-warn, r=nikomatsakis

Rename force-warns to force-warn

The renames the `--force-warns` option to `--force-warn`. This mirrors other lint options like `--warn` and `--deny` which are in the singular.

r? `@nikomatsakis`

cc `@ehuss` - this option is being used by Cargo. How do we make sure the transition to using the new name is as smooth as possible?

-# `force-warns`
+# `force-warn`
 
 The tracking issue for this feature is: [#85512](https://github.com/rust-lang/rust/issues/85512).
 
 ------------------------
 
-This feature allows you to cause any lint to produce a warning even if the lint has a different level by default or another level is set somewhere else. For instance, the `force-warns` option can be used to make a lint (e.g., `dead_code`) produce a warning even if that lint is allowed in code with `#![allow(dead_code)]`.
