In docs/17-common-problems-and-their-solutions.md, many of the subsections are out-of-date:

• The EOFException when using client classes is obsolete as it refers to the DynamoDB state store which is no longer the default and will be removed at some point. Suggest deleting this subsection.
• The I need to reinitialise a table section as written is misleading. Those instructions were from when deploying tables was done using cdk. This was slow and so these instructions were used to reinitialise a table without needing to use cdk. Suggest deleting this subsection.
• The Why is adding a table to an existing Sleeper instance so slow? section is obsolete - adding a table is no longer slow. Suggest deleting this subsection.
• The Out of memory error from standard ingest tasks section is still relevant but it probably needs updating as the properties refer to the array list implementation, not the Arrow one.
