What is the current behavior?

We currently haven't updated to TypeScript 5.5, this patch enables Renovate to trigger the dep update. Since we lowered the update rate, I went ahead and did the update myself and included it in this PR.

STENCIL-1264

What is the new behavior?

Allow renovate to update to TypeScript 5.5.

There are 15 unused exports on this PR. That's the same number of errors on main, so at least we're not creating new ones!

// Here we transform the TypeScript source from a commonjs to an ES module.
// We do this so that we can add an import from the `@environment` module.

// trim off the last part that sets module.exports and polyfills globalThis since
// we don't want typescript to add itself to module.exports when in a node env

Just curious, what changed so we don't need this anymore?

The TypeScript team made changes to make it easier consumable for ESM packages (see announcement). I tested it with an .mjs file, e.g.

import * as foo from './node_modules/typescript/lib/typescript.js'

console.log(foo);

And it worked great.
