Carl Meyer 3179b05221 [ty] don't assume in diagnostic messages that a TypedDict key error is about subscript access (#21166) ... ## Summary Before this PR, we would emit diagnostics like "Invalid key access" for a TypedDict literal with invalid key, which doesn't make sense since there's no "access" in that case. This PR just adjusts the wording to be more general, and adjusts the documentation of the lint rule too. I noticed this in the playground and thought it would be a quick fix. As usual, it turned out to be a bit more subtle than I expected, but for now I chose to punt on the complexity. We may ultimately want to have different rules for invalid subscript vs invalid TypedDict literal, because an invalid key in a TypedDict literal is low severity: it's a typo detector, but not actually a type error. But then there's another wrinkle there: if the TypedDict is `closed=True`, then it _is_ a type error. So would we want to separate the open and closed cases into separate rules, too? I decided to leave this as a question for future. If we wanted to use separate rules, or use specific wording for each case instead of the generalized wording I chose here, that would also involve a bit of extra work to distinguish the cases, since we use a generic set of functions for reporting these errors. ## Test Plan Added and updated mdtests.		2025-10-31 10:49:59 -04:00
