The release-cli tool supports the `ADDITIONAL_CA_CERT_BUNDLE` variable
for SSL certificate verification with custom CA certificates. Now, we
are adding an equivalent functionality to the glab CLI implementation.

When the `ADDITIONAL_CA_CERT_BUNDLE` environment variable is present:
- The certificate content is written to a file named
`ca_cert_for_releasing_with_glab.pem`
- The glab config is updated to use this certificate file
for the specific GitLab instance
- This configuration happens before authentication and release creation

This ensures both `release-cli` and `glab` CLI methods support
the same custom CA certificate functionality, maintaining parity as
we transition from release-cli to glab.

This change also updates the version requirement of `glab` to `v1.58.0.`
