chore(Tactic/Linter/TextBased/UnicodeLinter): update abbrevations

[SnirBroshi]

Ran the script on the latest commit (5a25e6a) of vscode-lean4, updated the dates and the commit reference.

leanprover/vscode-lean4@9ca2a82 added auto-closing abbrevations for existing characters which only caused stuff to shift around. The three new characters are ❰❱ from leanprover/vscode-lean4@7af7fa9 and ⦂ from leanprover/vscode-lean4@00a05fe.

I've also verified that all 97 chars in othersInMathlib are still in use.
