feat(dispatcher/env-http-proxy-agent): strip leading dot and asterisk

[SuperOleg39]

This relates to...

#4618

Rationale

no_proxy matching logic changes related to current behaviour in curl, deno and this specification - https://about.gitlab.com/blog/we-need-to-talk-no-proxy/

Changes

• strip leading dot, so no_proxy=.example.com is equivalent to no_proxy=example.com
• strip leading asterisk with dot, so no_proxy=*.example.com is equivalent to no_proxy=example.com
• drop support for substring suffix (this syntax is not specified anywhere), so no_proxy=*example is equivalent to no_proxy="" or the absence of a no_proxy variable

LGTM as far as I can tell from the blog post. Not sure if I should really use the approve button as I am not a undici collaborator but have write permission by chance here.
