Avalon 7.7.2 Release

[joncameron]

7.7.2 is a small patch release to 7.7.1 that includes two fixes: one for Ramp that fixes track information for "Add to playlist" (https://github.com/samvera-labs/ramp/pull/478), and one to fix an issue with thumbnail creation (https://github.com/avalonmediasystem/avalon/pull/5775). Other things that have been merged into develop shouldn't come over to staging for inclusion in 7.7.2.

@cjcolvar I created a combined upgrade page for 7.7.1/7.7.2: https://samvera.atlassian.net/wiki/spaces/AVALON/pages/2456289281/Upgrading+Avalon+7.7+to+Avalon+7.7.1+and+7.7.2. Does this make sense for these?

Created #5843 for deploying 7.7.2 to Demo.
