HTTPClient https request fails if no fingerprint is provided

[torntrousers]

As per the comment made after Issue 2197 was closed, it should be possible to use HTTPClient with an https url without a fingerprint.

Having the same request turns me to use WiFiClientSecure with more work to do

Hi. As I checked, this issue should be fixed some time ago (Is it the same? #1941) - looks like it works in 2.1.0 but later it doesn't and is still there in 2.3.0-rc2.
@olileger Can You send some code snippet how to rewrite HTTPClient into WiFiClientSecure?

This PR allows specifying '*' as the fingerprint to skip validation #3933

Currently bearssl is integrated. Although still experimental, it is strongly advised to migrate to it, because axtls is planned for deprecation, and then retirement.
Closing this.
