refactor(Combinatorics/SimpleGraph/Walk): simplify proof of "support_tail_of_not_nil" (#28967) The proof of the lemma named "support_tail_of_not_nil" is shortened. Since "support_tail" is not needed anymore, it is removed. @[deprecated (since := "2025-08-26")] sign is added for the removed "support_tail". The library references to "support_tail" are replaced with "support_tail_of_not_nil". To keep [@simp] on "cons_support_tail" and avoid the linter error, the [@simp] of "support_tail_of_not_nil" (previously on "support_tail") is removed. There might be a better way that I am missing, to deal with the linter error.
