Set Branch Specifier as parameter (adoptium#4585)

- If LIGHT_WEIGHT_CHECKOUT=true, set Repository URL explicitly and set Branch Specifier as parameter
- If LIGHT_WEIGHT_CHECKOUT=false, set both Repository URL and Branch Specifier as parameter

Once https://issues.jenkins.io/browse/JENKINS-42971 is fully resolved, we should remove LIGHT_WEIGHT_CHECKOUT parameter
as LIGHT_WEIGHT_CHECKOUT=true should always be set.

resolves: adoptium#4580
