Expand description

Validate the given crate name.

Note that this validation is more permissive than identifier parsing. It considers non-empty sequences of alphanumeric and underscore characters to be valid crate names. Most notably, it accepts names starting with a numeric character like `0`!

Furthermore, this shouldn’t be taken as the canonical crate name validator. Other places may use a more restrictive grammar (e.g., identifier or ASCII identifier).
