chore(helm chart test): tests can be run in environment with self-signed certificate

[iainsproat]

Description & motivation

Local development and CI environments may not have a domain name with a trusted certificate. Instead they are likely to have self-signed certificates. This caused the test container to fail when it attempted to connect to the speckle server under test.

Changes:

• introduces a VERIFY_CERTIFICATE environment variable
• will verify the certificate by default, but skip if the environment variable is set to "0" (Note, zero is a string value)
• bumps specklepy to 2.17.7, as this allows skipping of tls certificate verification
• visual improvement of logged output
