GithubMetaAnalyzer ignore repositoryUrl if repositoryPassword is empty

[ShuP1]

Current Behavior

GithubMetaAnalyzer still calls github.com even if a proxy URL is set in Administration > Repositories > GitHub

Note: unless a password is set https://github.com/DependencyTrack/dependency-track/blob/4.13.0/src/main/java/org/dependencytrack/tasks/repositories/GithubMetaAnalyzer.java#L124

Steps to Reproduce

1. In Administration > Repositories > GitHub, replace URL https://github.com with another URL. Do not set password
2. Let GithubMetaAnalyzer run
3. It fails because github.com is not reachable

Expected Behavior

Would use URL provided in settings
