Heads-up: usd 22.05a coming to Rawhide

[Ben Beasley]

In one week (2022-06-01), or slightly later, I will update the usd 
package to version 22.05a[1] in Rawhide. This package has downstream .so 
versioning and does not maintain ABI compatibility across releases in 
general, so this will come with an .so version bump. The only dependent 
package is blender; I will take care of rebuilding it in a side tag.
