Add example using OZ contracts in VSCode

Can you add more context to the example? I.e. explain what the solution is doing/what the problem is (you did that a bit in your linked comment) so it is easier to reproduce for project structures that do not follow the example exactly

I wanted to show an example of usage solidity.remappings settings.

{
  "solidity.remappings": [
    "@openzeppelin/=packages/contracts/lib/openzeppelin-contracts/",
    "ds-test/=packages/contracts/lib/forge-std/lib/ds-test/src/",
    "forge-std/=packages/contracts/lib/forge-std/src/"
  ],
  "solidity.packageDefaultDependenciesDirectory": "lib",
  "solidity.packageDefaultDependenciesContractsDirectory": "src",
}

The documentation indicates that for a non-standard project layout you need to change solidity.packageDefaultDependenciesDirectory and solidity.packageDefaultDependenciesContractsDirectory.
However, if solidity.remappings is configured correctly, these parameters do not affect anything. The import works equally well in both cases. Even if it's empty.

{
  "solidity.remappings": [
    "@openzeppelin/=packages/contracts/lib/openzeppelin-contracts/",
    "ds-test/=packages/contracts/lib/forge-std/lib/ds-test/src/",
    "forge-std/=packages/contracts/lib/forge-std/src/"
  ],
  "solidity.packageDefaultDependenciesDirectory": "",
  "solidity.packageDefaultDependenciesContractsDirectory": "",
}

I was looking for an answer to this question, and I wish it was in the documentation.
If you think this is redundant information, I don't mind.

Thank you.

Nono, I think it's fine - I was just asking for you to add some more context to the document itself so others can reproduce it for project layouts that do not necessarily match the example :) Imo there is more context in the original comment you posted in the other repository and some of that would be good here as well.

this is still valid for vscode, so still helpful
