New features

Tests + making fields translatable on install.

Changes since 8.x-3.0-alpha4:
#2956550 by Sivaprasad C, AohRveTPV: Fix dependency declaration
#2948046 by emartoni: Configuration link is wrong on README.md
#2843326 by aamouri, voleger: Missing use t() function for some messages
#2856294 by Znak: Deprecated methods

Since Search API Solr 8.x-2.x Search API Solr Multilingual has been merged to that module. But there was no automated upgrade path.
Due to the architectual changes it should be possible now to do an upgrade to Search API Solr 8.x-3.x.
Therefore this release is created to perform the required steps.
The module gets automatically deactivated after the upgrade and isn't required anymore afterwards.

To upgrade your system via command line, run

#3021682: File widget not showing up after removing file from a multiple registration managed field
