hed-validator v3.15.1

This version contains no substantive changes to the code. An indirect dependency was bumped to satisfy npm audit, and a GitHub Action was added to (hopefully) directly publish GitHub releases to npm. This should also remove an extraneous testing module that was left in several prior releases, which bloated their sizes.

What's Changed

• Bump get-func-name dependency to fix npm audit hit by @happy5214 in #160
• Publish npm releases from GitHub Actions by @happy5214 in #161
