Remove .d.ts post-process in deploy+migrate scripts (#2071)

It has not been needed for years but I never noticed because I forgot about these scripts and never used them.

This means that the types packages used for overriding the default DOM types have had AbortSignal.abort incorrectly disabled all this time, but it's rarely used (only a few repos per million at Google, at least), so nobody ever complained about it.
