runtime(ssh): ignore case in 'keywordprg', update syntax script
- ftplugin(sshdconfig): use "-I" for 'keywordprg' to search
case-insensitive in the man page
- syntax(sshdconfig,sshconfig): Mark "lowdelay", "throughput", and
"reliability" as deprecated for IPQoS, highlighting them as
errors/warnings to reflect OpenSSH 10.1p1 release
