Regression in @actions/http-client 2.2.0 since 2.1.1: Bundle size increased by 820kB

Regression in @actions/http-client 2.2.0 since 2.1.1: Bundle size increase by 820kB

In my case it increased from 320kB to 1130kB.

@actions/http-client is a dependency of @actions/core.

Since changes in @actions/http-client from version 2.1.1 to 2.2.0 the bundle size increased by 820kB as a result of adding the undici dependency to @actions/http-client.

Sorry to say, the @actions/core automatically installs the latest v2 of @actions/http-client which is now 2.2.0 and has terribly huge undici package.

Expected result

Replace the undici with something tiny. 820kB of source code to make http requests is ridiculous.

Additional Information

The root cause is here https://github.com/actions/toolkit/pull/1547 where the undici was added.

A lightweight HTTP client optimized for building actions

not "a lightweight" anymore.

Start by reviewing the @actions/http-client changes between versions 2.1.1 and 2.2.0, especially the undici addition in actions/toolkit#1547. Compare the generated bundle sizes and identify a smaller HTTP-client approach; done means preserving HTTP behavior while addressing the reported 820kB increase.
