support passing options to maven on-the-fly

[tomhmc]

Is your feature request related to a problem? Please describe. I would like to be able to pass a maven option on-the-fly e.g. -DdisableX=true

(currently our builds try and extract a git branch from the working directory, and it seems that the base branch audit is downloaded as an archive and untarred and results in bare code- we can disable this on the fly e.g. -DdisableX=true, but can't find a way to pass this into frogbot job)

Describe the solution you'd like to see

A JF_MAVEN_ARGS env var to pass options specific to the frogbot run

Describe alternatives you've considered

• MAVEN_ARGS is not supported until maven version 4.x.x - https://maven.apache.org/configure.html
• Options can be set in .mvn/maven.config but I don't want to generally apply those options to all builds.
• copying in maven.config with an earlier workflow step doesn't get used when auditing the base branch
