feat: added support cross app secret referencing

[nimish-ks]

Added support for secret referencing across applications.

Additional changes:

• chore: bumped dependencies
• fix: imports

@rohan-chaturvedi you may use the following script to access secrets:

from src.phase import Phase, CreateSecretsOptions, GetAllSecretsOptions, GetSecretOptions
import os
import json

phase = Phase(
    init=False,
    pss=os.environ.get('PHASE_SERVICE_TOKEN'),
    host='https://console.phase.dev'
)

get_options = GetAllSecretsOptions(
    env_name="Development",
    secret_path="",
    app_id="443b1987-caaf-4b68-ab47-7cd49ef4ed74"
)
secrets = phase.get_all_secrets(get_options)

# Create dictionary with all fields
secrets_dict = {
    secret.key: {
        'value': secret.value,
        'comment': secret.comment,
        'path': secret.path,
        'tags': secret.tags,
        'overridden': secret.overridden,
        'application': secret.application,
        'environment': secret.environment
    } for secret in secrets
}

# Print beautified JSON
print(json.dumps(secrets_dict, indent=4))

• Set the PHASE_SERVICE_TOKEN
• Replace the app_id

LGTM, everything working as expected. Needs a version bump though
