Description 📣

This PR resolves #206

I've always found it strange that I have to configure part of a project's infisical setup in .infiscal.json, and then another part with the $INFISICAL_API_URL environment variable. It makes complete sense that this static piece of data could live in the .infisical.json file and not feel out of place.

I've updated the CLI so that if apiUrl is defined in the .infiscal.json file, it's used, like so:

{
  "workspaceId":                   "ea1b0a5f-xxxx-xxxx-xxxx-a1ef1c323cc1",
  "defaultEnvironment":            "dev",
  "gitBranchToEnvironmentMapping": null,
  "apiUrl":                        "https://my.infisical.instance.com/api"
}

I've also ensured that precedence is preserved and makes sense. Precedence for specifying this value is as follows:

--domain flag → $INFISICAL_API_URL env var → .infisical.json → default value

NOTE If this PR is accepted and merged in, I'll issue another PR to update the CLI docs here to include documentation for these changes.
