* chore: migrate `src/Connection` to TypeScript This commit migrates `src/Connection` to TypeScript. It also changes its exports to be ESM because TypeScript's support for exporting values to use as types via CommonJS is poor (by design) and so rather than battle that it made more sense to migrate the file to ESM. The good news is that TypeScript is still outputting to `lib/` as CommonJS, so the fact that we author in ESM is actually not a breaking change at all. So going forwards we will: * migrate TS files to use ESM for importing and exporting * continue to output to `lib/` as CommonJS * continue to use CommonJS requires when in a `src/*.js` file I'd also like to split `Connection.ts` into two; I think the `CDPSession` class belongs in its own file, but I will do that in another PR to avoid this one becoming bigger than it already is. I also turned off `@typescript-eslint/no-use-before-define` as I don't think it was adding value and Puppeteer's codebase seems to have a style of declaring helper functions at the bottom which is fine by me. Finally, I updated the DocLint tool so it knows of expected method mismatches. It was either that or come up with a smart way to support TypeScript generics in DocLint and given we don't want to use DocLint that much longer that didn't feel worth it. * Fix params being required
