Fix configure scripts destroying restored Deno CI cache (#14450)

The CI Deno dev cache (Cache Deno development cache step in
.github/workflows/actions/quarto-dev/action.yml) restores
package/dist/bin/deno_cache before configure runs. configure.sh
and configure.cmd then unconditionally wipe package/dist when
bootstrapping Deno, destroying the just-restored cache before
vendor.sh reaches it. The vendor scripts already gate their own
cache wipe with QUARTO_SKIP_DENO_CACHE_WIPE=1; the configure-time
wipe was missed.

Apply the same gate to configure.sh and configure.cmd so the
restored cache survives. Local devs (env var unset) keep the
original wipe behavior.
