Description of the problem

hey!

i notice that atob and btoa are marked as Legacy, which states "no longer actively maintained, and other alternatives are available".

some notes on that:

1. they do seem to still be maintained:
   • ⁠optimized in april 2024: ⁠buffer: even faster atob #52443
   • recent bug fix: buffer: atob throw error when the input value is invalid #42662
2. the alternative listed is not an equivalent. atob and btoa are optimized at the C++ level, and do not create an in-memory Buffer in javascript context that then has to be garbage collected (needless, for instance, when ⁠ JSON.parse(atob(b64)))

having these marked as legacy also seems to go against the very good direction node has taken recently of compatibility with web apis like the webstreams api

i think it would be great if these were marked Stability 2! what do you think?
