Switch to esbuild and tsc instead of pika

[kfcampbell]

Replicating octokit/request.js#584 to another repo.

---

Pika has been deprecated for a while now, and the project has now been archived, and because of that the released npm package is missing most of the files generated by the build step.

Uses esbuild to transpile the TS source code into an ESM source, NodeJs bundle, and a browser bundle

Uses the TypeScript compiler to generate the types.

Behavior

Before the change?

• Uses pika for the build system
• The released npm package is missing most of the files generated by the build step. dist-node, dist-types, dist-web... even though they are generated correctly.

After the change?

• Uses esbuild to generate the JS bundles
• Uses the TypeScript compiler to generate the type definitions
• The correct file matching patterns are used so we publish all the necessary files again.

Don't forget to explicitly mark type imports and exports.

Whenever an imported value, that is also JS code, is only used as a type, it should be imported as a type, to make sure that it doesn't show up in the build output.

All typescript types (except for enum) need to be imported using type imports, and exports need to use the type export syntax.

@wolfy1339 I've updated this PR to correctly import types, bumped to the latest version of octokit/tsconfig, and fixed the merge conflict! Hopefully this is good to go now.

Hmm...locally I'm seeing:

Even after many reloads here, I'm not seeing the new commits:

I wonder if we're having issues.

[kfcampbell]

Yep, looks like that's it:

Looks like we're all good now!
