Release 2.5.1

[pwtyler]

CHANGELOG

• Fix Solr not indexing automatically [#598]
• Fixed issue with empty/zero value for posts_per_page [#599] (props @threeiem)
• Testing and automation improvements

[pwtyler]

Flipping to draft as I'd like to investigate a potential issue with commit cli command introduced in 2.4.0 before cutting a release.
