ANNOUNCEMENT - v6.2.0-beta3 released

[Fr. Samuel Springuel]

This fixes the last known blocking bug for the 6.2.0 release. Please test and report back any bugs you find. As this is being released at the beginning of Holy Week (a traditionally busy time for those interested in Gregorian Chant), we will won't be moving to a release candidate until after Easter.

## What's Changed
* Fix segfault on empty GRE_ELEMENT when nabc_state wraps mid-syllable (#1726) by @lbssousa in https://github.com/gregorio-project/gregorio/pull/1727
