Fall back to a module's release tag when its lockfile is broken

jaspDescriptives master has carried a stray "|" in renv.lock since
2026-10-07. The lockfile patch could not parse it, so the build stopped
after 85 minutes. A module whose renv.lock does not parse is now built
from its newest release tag up to the JASP version (jaspDescriptives
v0.98.1, the version the official 0.98.8 builds ship as well). The build
stops early if no such tag exists.
