Redact packse version in snapshots (#5483)

Every packse version update is currently causing a huge diff (the size
of the `lock_scenarios.rs` diff in this PR). By redacting the version
from the snapshots, we will only have the actual change in the diff and
not the redundant version change noise.

The second commit moves all remaining packse url arg values to
`common/mod.rs`, which acts as a single source of truth for the packse
version.
