esp32/boards: Remove references to the IDF version in board.md files.

Listing the IDF version number in the board description is not as important
as it once was, when the IDF was still undergoing a lot of changes.  Now,
all builds use IDF 5.x and it's possible to query the exact version with
platform.platform().
