Athena unload_approach issues

[jaidisido]

Describe the bug

I discovered a number of issues to address while using Athena unload_approach:

1. unload_approach input argument does not exist for athena.read_sql_table
2. Database and table names are not sanitised like for other approaches. For instance, a table name of amazon-reviews would fail because the Glue catalog only accepts underscore (amazon_reviews)
3. The query results location should not be the same as the query output location. This is because the query results location must a valid location for the Athena workgroup. In other words, if the specified output location is not a valid Athena workgroup location, the query fails

How to Reproduce

1. Attempt unload_approach in wr.athena.read_sql_table
2. Pass in an unsanitised database or table name
3. Pass an s3_output path which is not a valid Athena workgroup path
