[BUG] Path option doesn't seem to expand user

[felixgao]

Describe the bug

When the path have ~ in the path it doesn't seem to resolve.

To Reproduce

• Create a file main.py with:

import typer

app = typer.Typer()

@app.command()
def login(
    config_path: Path = typer.Option(
        default=os.environ.get("PROFILE", "~/.aws/my_profile"),
        exists=True,
        file_okay=True,
        dir_okay=False,
        readable=True,
        resolve_path=True,
    )
):
  typer.echo(f"Hello {config_path}")

if __name__ == "__main__":
    app()

• Call it with:

python main.py

• It outputs:

Error: Invalid value for '--config-path': File '~/.aws/my_profile' does not exist.

• But I expected it to output:

Hello ~/.aws/my_profile 

or

Hello /User/username/.aws/my_profile

Environment

• OS: macOS
• Typer Version: 0.3.2
• Python version: 3.6.12

Also expect to have a parameter control expanduser, and there are also some discussions in pallets/click#287.

The documentation is clear about this.

:param resolve_path: Make the value absolute and resolve any
    symlinks. A ~ is not expanded, as this is supposed to be done by the shell only.

So, I'm afraid it's a feature, not a bug.
