Maintain our actual/current software versions over time when Preservation Events are generated

[eporter23]

Goal: detect and record the currently installed version of software entries stored in Preservation Events so that we aren't recorded an older version of the software that performed the action.

For example, if our version of FITS is upgraded, we should record the version in use at Emory when creating a Characterization event.

This also occurred in 2023 when we had to upgrade to a new minor Fedora patch to address a vulnerability, causing our preservation events to temporarily reflect 4.7.5 instead of 4.7.6.

If we can't dynamically keep the version numbers updated, we should alternatively plan for a maintenance cycle.
