RunContext.cli_command assigns the short flag -y to both --yaml and --yes — click warns on every invocation

Summary

In RunContext.cli_command (nemo_run/cli/api.py, v0.9.0) two options claim the same short flag:

yaml: Optional[str] = typer.Option(None, "--yaml", "-y", help="Path to a YAML file to load"),        # L894
skip_confirmation: bool = typer.Option(False, "--yes", "-y", "--no-confirm", help="Skip confirmation before execution"),  # L899

so every invocation of any generated command prints:

UserWarning: The parameter -y is used more than once. Remove its duplicate as parameters should be unique.

(twice per parse: click/core.py make_parser and parse_args). Besides the noise, whichever option click resolves -y to wins silently — a user typing -y for "yes" may instead set yaml.

Minimal reproduction (nemo_run + typer only)

import warnings
import typer
from typer.testing import CliRunner
from nemo_run.cli.api import RunContext

def demo(x: int = 1) -> None:
    pass

app = typer.Typer()
RunContext.cli_command(app, "demo", demo)

with warnings.catch_warnings(record=True) as caught:
    warnings.simplefilter("always")
    CliRunner().invoke(app, ["demo", "--help"])

print(len([w for w in caught if "-y" in str(w.message)]))   # 4

Suggested fix

Drop -y from --yaml (the near-universal CLI convention reserves -y for yes/skip-confirmation), leaving --yaml long-form only.

Open nemo_run/cli/api.py and inspect the RunContext.cli_command options around lines 894-899. Run the minimal reproduction from the issue; done means --yaml remains available, -y selects the yes/skip-confirmation option, and the duplicate-parameter warnings no longer appear.
