fix(ext/net): implement a graceful error on an invalid SSL certificate (#20157)

The goal of this PR is to address issue #19520 where Deno panics when
encountering an invalid SSL certificate.

This PR achieves that goal by removing an `.expect()` statement and
implementing a match statement on `tsl_config` (found in
[/ext/net/ops_tsl.rs](https://github.com/denoland/deno/blob/e071382768fa57b5288a6a5ba90e73bf5870b169/ext/net/ops_tls.rs#L1058))
to check whether the desired configuration is valid
