Update eslint-config-wikimedia

    npm i --engine-strict eslint-config-wikimedia@latest

And disable all the warnings for various reasons. I don’t find
n/no-unsupported-features/node-builtins useful at all – if the features
in question (global fetch, FormData, buffer.File, Response) were
declared experimental on the older Node versions we target, but have
since been stabilized in a stable release, and already work in the older
Node versions, then I think it’s fair to consider them supported there
too: I don’t see why they would be broken in newer releases on those
older branches. (And CI already checks that they work in the oldest Node
we target.) implicit-arrow-linebreak would require either an overlong
line or converting the expression into a block, neither of which I like
in combineParams(). And prefer-arrow-callback is explained in the
disable comment.

Also note that in the last two commits I used the npm option with a
wrong name – it’s --engine-strict, not --engines-strict. Apparently npm
silently ignores unknown options. (AFAICT it didn’t make a difference
for those particular commits anyway.)
