Postgresql SSL Remote connection seems to fail and ignores skip validation

In PMM-Version 2.33.0 RC candidate, our automation tests fail when trying to add a local SSL setup, we add the instance with remote UI and ensure to skip Certificate validation, but still end up getting an error message

This seemed to work fine on 2.32.0 and prior versions, so this is a regression. 

STR: 

Please setup pmm-server 2.33.0-rc and client rc, using perconalab/pmm-server:2.33.0-rc 
1) Setup postgresql with SSL/TLS

2) Generate certs, (you can use --setup-postgres-ssl on staging start job to re-use our setup)

3) Certificates are present under (/srv/pmm-qa/pmm-tests/tls-ssl-setup/postgres/15) directory if you used staging instance. 
4) Open remote instance page, try adding postgres instance using SSL flags. 

Expected Results:

Instance is added for monitoring

Actual Result:

Error about certification hostname validation
