fix(ci): correct <picture> to PNG replacement regex and extend Open VSX verification timeout

The package-vsix.cjs script was replacing <picture> blocks with .png URLs but
the actual filenames are banner.png and architecture.png, not banner-light.png
or architecture-dark.png. The regex now strips -light/-dark suffixes before
applying .png extension.

Also increased Open VSX verification from 18 attempts (3 min) to 54 attempts
(9 min) to account for slower indexing times.
