Broken links caused by ethclient upgrade

[syntrust]

Now web3url-gateway uses https://github.com/web3-protocol/web3protocol-go as web3:// engine.

The package now use a up-to-date go-ethereum dependency, and they recently are now using "input" instead of "data" in the JSON-RPC call (apparently "data" was kind of supported but was not the standard). Cf ethereum/go-ethereum#28078 As a consequence, several tests to blockchains ids 1666600000, 1666700000, 100001, 1088, 599, 84531 fails because their RPCs does not recognize "data".

We may need to consider the downgrade of go-ethereum for backward compatibility.

Broken links that were accessible using the old version gateway:

And here is the backport of go-ethereum (a few months back) so that it uses "data" again, unbreaking these RPCs. (tests added back, all tests are passing)
PR -> #17

#17 is deployed and the links are working now.
