Update project: beartype

[JWCS]

Update details:

• Project Name: beartype

Category Change: "Linters and Style Checkers" -> "Typecheckers"

Additional context:

The beartype project is currently listed under "Linters and Style Checkers"; but it's clearly a (static/runtime hybrid) "Typechecker" (in fact, arguably the only correct typechecker for that, which is more ironic).
