fix: improve createHmacSignatureAsync compatibility with worker-based environments (#573)

Worker-based environments (e.g. `jest` tests) do not have access to
`globalThis.require()` (while calling `require()` instead works). Deeper
investigation shows that `tsup` doesn't transpile this in a dangerous
way, so we can use this here.

Unblocks apify/apify-client-js#782 (tested)
Unblocks failing tests in #570
