Improve Documentation

[vGsteiger]

Is your feature request related to a problem? Please describe.
The documentation could be improved for better clarity and usability. It is currently frustrating when trying to deploy and execute the small_sync_example due to unclear instructions and missing details.

Describe the solution you'd like

• Clear Expected Output: Specify the expected output for each step and where to find it (e.g., which DynamoDB table to check, which CloudWatch log group to review).
• Early Introduction of Concepts: Introduce the concept of workflow_id earlier in the documentation.
• Prerequisites: Include Python version requirement (3.12+), mention the need to install crane, and the necessity of exporting keys early on (highlight the installation guide better).
• Memory Limit Clarification: Explain the memory constraints for poetry run caribou deploy_remote_cli and provide a working default (apparently everything above 3008 fails).

Regarding "Memory Limit Clarification" issue, this may be related to AWS setting a limit for new AWS accounts, this can be solved by contacting AWS support.

See the following Posts:

• https://repost.aws/questions/QUiKQO44fIT6OeVlDi8ejg8g/cannot-set-lambda-memory-larger-than-3gb.
• https://repost.aws/questions/QUKruWYNDYTSmP17jCnIz6IQ/questions/QUKruWYNDYTSmP17jCnIz6IQ/unable-to-set-lambda-memory-over-3008mb?

But in a previous PR, we already reverted the defaults to be under this limit.

If we are already below that threshold then we can just remove that.
