feat!: bump engines to Node.js >=22.12.0

[erickzhao]

BREAKING CHANGE: bumps minimum Node.js version to >=22.12.0

Dependency upgrades

Node.js 22.12 gives us the ability to use CommonJS require calls on ESM dependency graphs. This gives us the ability to upgrade got and env-paths past their last CJS version without using a dynamic await import, which isn't tenable in a few cases.

Removal of deprecated APIs

@electron/get already had a few deprecated APIs and this PR removes them since we're already making a breaking change anyways:

• nightly_mirror option was removed (was deprecated in favour of nightlyMirror)
• force option was removed (was deprecated in favour of cacheMode=WriteOnly).

Test migration from Jest to Vitest

Jest currently has issues with require(esm) while it works out of the box with Vitest. We were already looking to migrate to Vitest across other Ecosystem repos, so this PR just switches over.

• Need to import functions from vitest (no globals)
• jest.mock calls turned into vi calls
• Regenerated snapshots

tsconfig.json changes

We're now basing our TypeScript config off of @tsconfig/node22, which is a bit different from what we had in the past.

• skipLibCheck: true was added due to an incompatibility with got@14.
• CJS compilation now updated to module: node16 and moduleResolution: node16.
• ESM compilation kept at module: esnext and moduleResolution: node10.

Note: this new clause is needed because fs.rename will fail if the target directory doesn't exist, while fs.move creates the directory.

This also doesn't work across disks, but we could catch the resulting error and fall back to an fs.copy call if necessary.
