Editorial: Store ToString(𝔽(k)) in a variable for consistency

[yossydev]

ToString(𝔽(k)) was sometimes stored in let Pk and sometimes not. While this does not affect behavior, for consistency in the specification, I have standardized it to be stored in a variable.

Fixes #3530

I don't like doing this in places where the alias would only be referred to once. I am okay with indexOf and lastIndexOf because the alias is referred to twice in those AOs.

Thank you!
I have only modified indexOf and lastIndexOf.

Would it be better to upgrade the version?

@yossydev That's happening elsewhere; don't worry about it here.
