Add SDK Version to AWS Lambda Layer description

[antonpirker]

Currently there is no way for users to figure out what version of the Sentry SDK is included in the Lambda Layer they put onto their Lambda function.

See:

Add the SDK version as nicely written string to the description of the Layer version to make the SDK version visisble.

This is also listed as "Option B" in this issue: #3905

I did some research. If we want to set the description (would also be nice: the "compatible architectures") we need to update Craft so we can set those fields in the Lambda layers.

Additionally we then also need to get the SDK version somehow into craft.yml so we can set it as the description...

tl;dr: It's complicated.
