Add support for Solidity

[come-maiz]

Please, add support for Solidity, the most common language to write Ethereum smart contracts.

Thank you <3

maybe in the future - since the language is not very popular it has a very low priority sry

[come-maiz]

I understand. And the default highlighting doesn't look bad, so thanks for that!

hello we are in 2023, have things evolved? Thank you

contributions are welcome - implementing a new language takes about one day (creating the testcases and gathering most language elements is very time consuming).

please keep in mind that the whole Enlighter project does only have 1 dev/maintainer...
