EmbeddedContentButton regex produces a warning

Problem/Motivation

An invalid regex in the meetsCondition method of EmbeddedContentButton will produce a warning, this results in a lot of log noise even though it's in a try catch block

Warning: preg_match(): Delimiter must not be alphanumeric, backslash, or NUL in Drupal\embedded_content\Entity\EmbeddedContentButton->meetsCondition() 

Proposed resolution

Suppress error messages as well as ignoring exceptions.
