melting-pot.sh: use valid short property names

ctrueden · ctrueden · commit 75fc655f5bc1 · 2024-10-06T12:12:09.000-05:00
There are some artifactIds that begin with a digit rather than a letter,
which results in invalid version property names. Prepending the property
name with underscore avoids the issue.
