Fix to allow --detect.excluded.directories to work correctly again with wildcards like v7

[isaac84]

Don't escape asterisk '*' in DetectScriptStrategy so wildcards can correctly work again for --detect.excluded.directories
See https://community.synopsys.com/s/article/detect-excluded-directories-doesn-t-work

The workaround wasn't an option for us as unfortunately our repo is messy and there are about 100 directories that need to be excluded. Using a static list would be unmaintainable in our situation.

Testing done

Updated the existing DetectScriptStrategyTest to verify that '*' are not escaped, and tested this then allows the --detect.excluded.directories option to work correctly in our Jenkins builds (it does). Note: however we build with Linux so powershell was not tested in Jenkins.
