Initially this was going to be an update to dependencies but it seems i got a little carried away!

Anyways this PR removes 2 unused dependencies (`jshint` and `utf-8-validate`), and 2 other, `del` and `fs-extra` that were replaced by the built-in `fs/promises`.

It also renames all `tsconfig` and `Dockerfile` files, in a way that when viewed in a file tree sorted alphabetically they will be next to each other.

It also updates the typescript target to `ES2022`, and changes moduleResolution from `Node` to `Node10` (this isn't an update, they are the same thing but `Node` is now deprecated).

It also adds the `node:` discriminator to every import from built-in modules.

It also has major changes to the build script, `del` and `fs-extra` were only being used in the build script, it's now using `fs/promises` instead, cleaned up the code from some functions, adds better documentation to a few functions, and renames some gulp tasks and npm scripts to better represent what they actually do.

And finally it updates dependencies, except for `atomically` which can't be updated unless the project switches to ESM.
