ed 2d6eb63fce scripts/uncomment: python 3.12 support; ...

`tokenize.FSTRING_MIDDLE` was introduced, changing the
representation of `f"x{{y"` from `STRING(f"x{{y")` to:

* `FSTRING_START('f"')`
* `FSTRING_MIDDLE('x{')`
* `FSTRING_MIDDLE('y')`
* `FSTRING_END('"')`

each literal `{` (encoded as `{{` in the input) now appears as a
single `{` as the final character of its `FSTRING_MIDDLE`, with
additional consecutive `FSTRING_MIDDLE` tokens if necessary

regular interpolating `{` are encoded as separate `OP` tokens

the fact that the literal `{` is encoded as a single `{` instead
of `{{` breaks the assumption that the string-value of each token
maps directly to the original code

fix this by replacing `{` with `{{` and `}` with `}}` in
`FSTRING_MIDDLE` tokens, and not adding whitespace after
`FSTRING_MIDDLE` tokens
