[BUG] docker rustls TLS version/cipher suite/`--insecure` mismatch handling

[0x7274]

Describe the bug
This is clearly an edgecase, seemingly not yet discovered.

My current suspicion is, that rustls seems to not honor if --insecure cert or if TLS versions | cipher suites mismatch.

To Reproduce

1. feroxbuster docker image
2. transparent proxy to burpsuite with burpsuite certificate installed (works perfectly with curl, wget & other tools)
3. the site to scan
4. -> --insecure cert/TLS version/cipher suite mismatch (happens only on some sites where those mismatch)

Expected behavior
A more descriptive output why the handshake/connection failed -> currently most likely culprit being rustls having issues with --insecure/handling of the certificate provided (which should be ignored due to --insecure

Environment (please complete the following information):

• feroxbuster version: feroxbuster/2.13.0
• docker

Additional context
There are some sites I tested, that work correctly & some sites don't -> it's currently quite difficult to better troubleshoot & the most likely culprits/differences are listed above (but ofc, maybe there is something I've overlooked) -> If this is generally already known or can't feasibly be fixed, please let me know, so I can build a workaround 👍

thanks for reporting this!

the underlying http client (reqwest/hyper) no longer exposes exact lower level errors. i've looked into trying to dig out better errors for tls issues in the past and have come up empty handed. I'll take another look to see if this might be a different case, but i'm not terribly hopeful
