Please fix documentation in dns_knot.sh for KNOT_KEY

[StanZanarotti]

The dns_knot.sh script claims that KNOT_KEY is "File path to TSIG key", when in actuality it needs to be the key data itself.

This is referenced in issue #4450 -- the third comment from the end by stokito references this fact.

The documentation at https://github.com/acmesh-official/acme.sh/wiki/dnsapi#dns_knot says:

export KNOT_KEY='/etc/knot/acme.key'

where it should be something like:

export KNOT_KEY=hmac-sha256:example.com:dKOVNWnxMTRY9cXKg4X5b/IVo3sbuArOE4eUvrwMx/M=

You could also decide to update the script to accept a key file parameter and use the "-k" option in knsupdate to send it to the server.
This would keep the key from being passed in an environment variable.

Please upgrade to the latest code and try again first. Maybe it's already fixed. acme.sh --upgrade If it's still not working, please provide the log with --debug 2, otherwise, nobody can help you.
