support/scripts/pkg-stats: make current version cell scrollable

Currently, when the version string is "too long", it is arbitrarily
truncated.

This works well for commit hashes, because usually the truncation is
long enough to provide a short hash that is still unique in the
upstream VCS.

However, there are non-hash-like versions strings that get truncated
and wihch the discriminant part is toward the end.

Yet, adapting the version cell to the widest versions string (most
probably a git hash) is not very interesting; the table is already very
large.

Make the cell with the version string scrollable: we get to keep the
best of both worlds: a narrow version cell, and a full-length version
string that can be copy-pasted if needed.
