Update other packages to use http-client v2 (#1082)

We moved `@actions/http-client` to be part of the toolkit in https://github.com/actions/toolkit/pull/1062.  We also made some breaking changes to exported types and released v2.

The biggest change in terms of lines of code affected was to get rid of the `I-` prefix for interfaces since TypeScript doesn't follow this convention.

I bumped the patch version of all packages except for `tool-cache`, where I bumped the major version.  The rationale is explained in the release notes for that package.
