Update season schedule parser to return ET time, instead of UTC

[imponenm]

Updating season schedules to return ET time instead of UTC. This makes sense because when using client functions that query with a game date (year/month/day), they are checking the ET times on Basketball Reference.

As a more concrete example: Currently - if I first query for a list of games in 2024, then use those dates to query box scores, I would miss games unless I convert all the returned datetimes to ET

After this update - Users will not have to convert the datetimes returned from the season schedule query
