v3.0.0 release announcement

[cmdcolin]

This is a major version bump mainly as a signal of potential breakage due to the upgrades of some dependencies, notably:

• React 18-> React 19 in jbrowse web (and loss of support of React <=17 for embedded devs)
• generic-filehandle -> generic-filehandle2 (which has a slightly different API)

There are not a ton of other changes otherwise. This major version bump is similar to our decision to major version bump in our "v2.0.0" release https://jbrowse.org/jb2/blog/2022/07/07/v2.0.0-release/

This loses our "vanity version number" of v2 to correspond to JBrowse 2. We can continue calling it "JBrowse 2 v3.0.0" or we can just say "JBrowse v3.0.0" (https://paulrrogers.com/2014/09/vanity-versioning/)

if there is a particular branding that is preferable, we could discuss.
