fix: content overload signatures (#290)

Simplifies or, in most cases, corrects the overload signature. Variable
names and documentation are updated along the way.

- Renames `kwargs` based on context. The variable name `conditions` is
introduced for querying methods. The variable name `attributes` is
introduced for record manipulation. This also signifies that this is not
a passthrough method.
- Documentation is updated to reflect the current state of Posit
Connect.
- Removes deprecations for field names in integration tests.

Resolves #140
