docs: update typescript.md

[nyedidikeke]

"You SHOULD NOT remove nor edit it" in place of "You cannot remove it or edit it".
Rational:

• It is a strong recommendation; not a weak possibility.
• Both actions have a negative connotation; as such, it is appropriate to use "nor".

Usually “nor” follows “neither”

I think the existing sentence is correct as is, because according to Bryan Garner, “the initial negative carries through to all the enumerated elements”

I saw there was a comment made, dismissing my approval.
