Old version of WorkManager is used, which causes R8 issues with AGP9

[WonderCsabo]

This library pulls in a really old version of WorkManager: 2.7.1 . That version has an issue with AGP 9 and R8, which causes the app to crash at startup.

That issue was already fixed in WorkManager. Update the version in this library, so it does not causes this transitive crash.

Thank you for the report @WonderCsabo.

We will check our possibilities with the Work Manager.

Let me point out that according to the READ.ME (https://github.com/exponea/exponea-android-sdk#support) the official reporting channel is through Engagement Support Scope to be correctly prioritized and addressed.
