Should we enable the check CheckedExceptionNotThrown in error prone?

This check prevents methods that do not throw a specific exception to declare they do. I think this would be beneficial for Lucene as many method implementation declare they throw IOExceptions when they do not perform any IO making consumer of those methods to have to handle this exceptions when they shouldn't.

Change is trivial but it touches many files.

Start by locating Lucene's Error Prone configuration and determine how the CheckedExceptionNotThrown check is enabled. Review the resulting diagnostics across the affected methods, remove declarations that no longer apply, and run the relevant build and test checks to confirm the project remains clean.
