Mark the Mojos as thread-safe

[nikita2206]

📜 Description

Just marks the Mojos as thread-safe, this reduces the WARNING-level logging by Maven when running multi-threaded builds:

| [INFO] --------------------------------[ jar ]---------------------------------
| [WARNING] *****************************************************************
| [WARNING] * Your build is requesting parallel execution, but this         *
| [WARNING] * project contains the following plugin(s) that have goals not  *
| [WARNING] * marked as thread-safe to support parallel execution.          *
| [WARNING] * While this /may/ work fine, please look for plugin updates    *
| [WARNING] * and/or request plugins be made thread-safe.                   *
| [WARNING] * If reporting an issue, report it against the plugin in        *
| [WARNING] * question, not against Apache Maven.                           *
| [WARNING] *****************************************************************
| [WARNING] The following plugins are not marked as thread-safe in %module-name%:
| [WARNING]   io.sentry:sentry-maven-plugin:0.2.0
| [WARNING]
| [WARNING] Enable debug to see precisely which goals are not marked as thread-safe.
| [WARNING] *****************************************************************

💡 Motivation and Context

My understanding is that Sentry's plugin is in fact thread-safe, but was just never marked as such. Avoiding the warnings would help us, as we are paying attention to other warnings that are mainly coming from the Checkstyle plugin and having these mixed makes it harder to notice to those.
