reuse: add copyright + license info to individual docs/*.md files
Instead of use 'docs/*.md' in dep5. For clarity and avoiding a wide-
matching wildcard.

+ Remove mention of old files from .reuse/dep5
+ add info to .github/dependabot.yml
+ make scripts/copyright.pl warn on non-matching patterns

GHA: add a job scanning for "bad words" in markdown
This means words, phrases or things we have decided not to use - words that
are spelled right according to the dictionary but we want to avoid. In the
name of consistency and better documentation.

gskit: remove
We remove support for building curl with gskit.

 - This is a niche TLS library, only running on some IBM systems
 - no regular curl contributors use this backend
 - no CI builds use or verify this backend
 - gskit, or the curl adaption for it, lacks many modern TLS features
   making it an inferior solution
 - build breakages in this code take weeks or more to get detected
 - fixing gskit code is mostly done "flying blind"

This removal has been advertized in DEPRECATED in Jan 2, 2023 and it has
been mentioned on the curl-library mailing list.

It could be brought back, this is not a ban. Given proper effort and
will, gskit support is welcome back into the curl TLS backend family.

b4f9ae5126 schannel: fix user-set legacy algorithms in Windows 10 & 11
- If the user set a legacy algorithm list (CURLOPT_SSL_CIPHER_LIST) then
  use the SCHANNEL_CRED legacy structure to pass the list to Schannel.

- If the user set both a legacy algorithm list and a TLS 1.3 cipher list
  then abort.

Although MS doesn't document it, Schannel will not negotiate TLS 1.3
when SCHANNEL_CRED is used. That means setting a legacy algorithm list
limits the user to earlier versions of TLS.

Prior to this change, since 8beff435 (precedes 7.85.0), libcurl would
ignore legacy algorithms in Windows 10 1809 and later.

67d3afa73f schannel: Support strong crypto option
- Support enabling strong crypto via optional user cipher list when
  USE_STRONG_CRYPTO or SCH_USE_STRONG_CRYPTO is in the list.

MSDN says SCH_USE_STRONG_CRYPTO "Instructs Schannel to disable known
weak cryptographic algorithms, cipher suites, and SSL/TLS protocol
versions that may be otherwise enabled for better interoperability."

schannel: support selecting ciphers
Given the contstraints of SChannel, I'm exposing these as the algorithms
themselves instead; while replicating the ciphersuite as specified by
OpenSSL would have been preferable, I found no way in the SChannel API
to do so.

To use this from the commandline, you need to pass the names of contants
defining the desired algorithms. For example, curl --ciphers
"CALG_SHA1:CALG_RSA_SIGN:CALG_RSA_KEYX:CALG_AES_128:CALG_DH_EPHEM"
https://github.com The specific names come from wincrypt.h
