Currently pgcat cannot be built on loongarch64 cpu, but that is easily fixable ;)

Describe the solution you'd like
Update dependencies that require ring crate older than 0.17
To be precise those are:

• webpki-roots (chore(deps): bump webpki-roots from 0.23.1 to 0.26.7 #877)
• tokio-rustls (chore(deps): bump tokio-rustls from 0.24.1 to 0.26.1 #881)
• rustls version 0.22+. There are some breaking changes but there is also helpful changelog to fix those: Prepare 0.22 rustls/rustls#1651
• nix 0.27.0+

Describe alternatives you've considered
None, I think updating few dependencies is the way

Additional context
loongarch64 is a cpu architecture which is supported by rust compiler and modern crate versions such as ring, linux-raw-sys, nix and others.
