Parser error on 1+/**/1

[piegamesde]

nixfmt chokes on (1+/**/1) with "unexpected '+'; expecting expression". However, (1+ /**/1) works just fine

bug is here:

https://github.com/serokell/nixfmt/blob/c123d0a725cc916a467934a7db88c3d3a0ba88eb/src/Nixfmt/Parser.hs#L295-L297C5

In particular, operators can be followed by other operators.
Also failing: (1+.4)

So, is the fix to simply remove the notFollowedBy (oneOf opChars)?

The idea behind it was to prevent parsing ++ as + + and // as / / so something still needs to check for that.
