chore(deps)(deps-dev): bump @biomejs/biome from 1.9.4 to 2.1.0

[dependabot]

Bumps @biomejs/biome from 1.9.4 to 2.1.0.

Release notes

Sourced from @​biomejs/biome's releases.

Biome CLI v2.1.0

2.1.0

Minor Changes

• #6512 0c0bf82 Thanks @​arendjr! - The rule noFloatingPromises can now detect floating arrays of Promises.

  Invalid examples

  // This gets flagged because the Promises are not handled.
  [1, 2, 3].map(async (x) => x + 1);

  Valid examples

  await Promise.all([1, 2, 3].map(async (x) => x + 1));

• #6637 6918085 Thanks @​arendjr! - Type inference is now able to handle the sequence operator (,), as well as post- and pre-update operators: ++.

  Example

  let x = 5;
  // We now infer that x++ resolves to a number, while the expression as a whole
  // becomes a Promise:
  x++, new Promise((resolve) => resolve("comma"));

• #6752 c9eaca4 Thanks @​arendjr! - Fixed #6646: .gitignore files are now picked up even when running Biome from a nested directory, or when the ignore file itself is ignored through files.includes.

• #6746 90aeead Thanks @​arendjr! - biome migrate no longer enables style rules that were recommended in v1, because that would be undesirable for users upgrading from 2.0.

  Users who are upgrading from Biome 1.x are therefore advised to first upgrade to Biome 2.0, and run the migration, before continuing to Biome 2.1 or later.

• #6583 d415a3f Thanks @​arendjr! - Added the nursery rule noMisusedPromises.

  It signals Promises in places where conditionals or iterables are expected.

  Invalid examples

  const promise = Promise.resolve("value");
  // Using a Promise as conditional is always truthy:
  if (promise) {

... (truncated)
