Reduces dependencies and version check logic (#13)

This commit does the following:

* Removes `@httptoolkit/esm` dependency, no longer needed as of `baseline-browser-mapping` v2.5.0 release.
* Removes `compare-versions-warning.js` and `compare-versions` module it depended on as `baseline-browser-mapping` warns about data staleness already.
* Removes `update-last-updated.js` script and references to it as it is no longer necessary.
