feat(linter): allow use of private dependencies from GCPAR in pre-commit

[santiagofdialpad]

Summary

This PR modifies the linter orb to install gcloud and authenticate in order to allow installing private dependencies in a pre-commit hook

We use our gcloud orb for those steps, which are only executed when a gcp_project is specified in the parameters.

Example of usage:

## File: .circleci/config.yaml

jobs:
  - linter/pre-commit: &pre-commit
      executor: python
      gcp_project: <GCP_PROJECT>

## File: .pre-commit-config.yaml

-   id: asd
    name: my-name
    language: python
    entry: command
    pass_filenames: false
    additional_dependencies:
        [
            '--extra-index-url=<PRIVATE_REPO_URL>',
            PACKAGE_TO_INSTALL,
        ]
