improve: type extension recognition for HardhatRuntimeEnvironment

[grasphoper]

Problem:

deployments, ethers, getChainId don't get recognized by Typescript language server and give red squigglies, which makes hre hard to work with. This happens in multiple places in the contracts repo.

Solution:

Add tasks/ and deploy/ to include section in tsconfig.json. https://www.typescriptlang.org/tsconfig/#include

It makes the language server "include" these folders and resolve types properly for them. This shouldn't have any side effects. The only one I can guess is npm package, which should be fixable by .npmignore. But I checked the yarn pack output, and the tasks/ and deploy/ folders stayed similar to our current npm package.

Edit: after looking at CI output, I realize that I'd have to fix a lot of TS linter errors before this can go in. Do you guys think it's worth doing? 😄

I think its something you can do if you have spare capacity, but not urgent!
