Add `sf deploy` options file to `.gitignore`

[cristiand391]

What does this PR do?

Adds the sf CLI deploy options file to .gitignore

Context:

The sf deploy commands allows the user to save the deploy options in a deploy-options.json file. If you choose to save it, it writes it at the root of the sfdx project but the file shouldn't be commited to the project as it contains the org username, test level, etc:

{
  "Salesforce Apps": {
    "testLevel": "NoTestRun",
    "username": "test-hehehehe@example.com",
    "apps": [
      "force-app"
    ]
  }
}

Good callout!

@pozil It looks like that the config files like .gitignore are not updated to what is set up for new projects.

Thanks for letting us know @cristiand391. I'll keep this PR open for now but I'll need to apply this to all sample apps in a scripted update.

I'll also add .env since the CLI may use this in the future for the string replacement feature.

I aligned and updated .gitignore files for all sample apps. Thanks again for raising this issue.
