[MNG-8694] Fix version interpolation and ternary operator (#2272)
Use the interpolator service instead of regexp for version interpolation
and fix the interpolator to properly support both `:+` and `:-` in the same
expression to support a ternary operator.
When processing ternary expressions like ${release:+${foo}:-${bar}} or
${versionCore}${release:+-DEVELOPER}, the DefaultInterpolator was incorrectly
continuing to process subsequent operators after a decision had been made on
the first operator.
This fix adds a break statement after each successful operator evaluation
to stop processing any remaining operators once a decision has been made,
ensuring that:
1. When 'release' is true and 'foo' is empty, correctly evaluates to an
empty string
2. When 'release' is true, correctly evaluates to just
Added test cases to verify both scenarios.
