Change "HTTP/3" to "HTTP/3.0".

[aaronriekenberg]

See caddyserver/caddy#4819 for context.

go's http.ParseHTTPVersion is unable to parse HTTP/3. This causes issues when using caddy as a reverse proxy to a go fastcgi server using net/http/fcgi.

Found instances of "HTTP/3" to change using grep:

grep -r '"HTTP/3"' *

Thank you!

[mholt]

Very nice, thanks! When should we update Caddy to get this patch?

[marten-seemann]

@mholt Sorry for the late reply. We'll be releasing a new minor version (v0.28.0) in the next couple of days.

[mholt]

No worries, and that's great, thanks!
