Unify quoting in metadata.xml files for machine processing

Force unified quoting in all metadata.xml files since lxml does not
preserve original use of single and double quotes. Ensuring unified
quoting before the process allows distinguishing the GLEP 67-related
metadata.xml changes from unrelated quoting changes.
