Improve build/generate-sri.js regex (#29753)

When using single-quotes in config.yml, the previous
regular expression in build/generate-cli.js wasn't working correctly,
it was replacing ALL string values with hashes.
Now both double- and single-quotes can be used in config.yml,
and the RegExp will work as expected.

Also, allow trailing whitespaces and empty ("") values to be matched.
