add support for .npmrc noproxy

[stefdev49]

Add support for 'noproxy' from .npmrc (https://docs.npmjs.com/cli/v9/using-npm/config#noproxy)
and have it takes precedence over no_proxy in .npmrc.

noproxy is npm's documented way of specifying non proxied hosts and domains.

@Rob--W axios user here. Looking for noproxy support for npm v9. Can you please take a look at this PR?

[Rob--W]

I have looked into this, and it appears that no_proxy was renamed to noproxy in npm/cli#46 in response to the feedback that the --no-proxy option was not working as expected at https://web.archive.org/web/20211028044200/https://npm.community/t/no-proxy-missing-from-npm-cli/1327.html .

I'll re-examine the addition from #9, update the library if needed + document the npm config variables as appropriate.

[Rob--W]

As part of maintenance, I'm going to carefully examine the set of changes, and then publish 1.2.0 or even 2.0.0.

The proposed change here has potential to cause breakage, e.g. as seen in #13 after support for npmrc was introduced in #9.

As one of the first steps, I'm going to update the CI in #20.

Due to other obligations I cannot work on this before next month (May).
