Bump ts-pattern from 4.0.6 to 4.2.1

[dependabot]

Bumps ts-pattern from 4.0.6 to 4.2.1.

Release notes

Sourced from ts-pattern's releases.

v4.2.1

Bug fixes

This release fixes inference of P.array when the input is a readonly array (issue #148)

declare const input: readonly {
  readonly title: string;
  readonly content: string;
}[];
const output = match(input)
.with(
P.array({ title: P.string, content: P.string }),
//      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
//              Used to error, now works
(posts) => 'a list of posts!'
)
.otherwise(() => 'something else');

v4.2.0

Features

Better inference for match and .with

match

When using match with an inline array, it will now infer its type as tuple automatically, even when not using as const. This means that exhaustiveness checking will also improve in this case:

function f(a: boolean, b: boolean) {
  // infered as `[boolean, boolean]`
  return (
    match([a, b])
      // we can pattern match on all cases
      .with([true, true], () => false)
      .with([false, true], () => true)
      .with([true, false], () => true)
      .with([false, false], () => false)
      // ✅ Failed in TS-pattern v4.1 but works in v4.2!
      .exhaustive()
  );
}

.with(...)

Thanks to the help of @​Andarist, this release fixes a long-standing issue of .with. Until now, patterns like P.array, P.union or P.when didn't have proper type inference when used in .with() directly. Here are a few behaviors that use to be incorrect and work now:
