Kp/adds root pulumi ai command

[kpitzen]

Description

This PR is intended to add the beginnings of a set of pulumi ai commands to the Pulumi CLI. The first implementation is relatively straightforward - we want to be able to open the Pulumi AI app from the CLI while providing a simple set of operations for users - pre-filling the AI prompt, and optionally not running that prompt when the page is opened. The CLI should open the appropriate URL in the user's default browser, and the app should take over from there.

This was implemented as a subcommand for pulumi ai as we intend to add more features both as siblings and at the parent pulumi ai command in the future, as this current functionality does not represent the "final default" experience we'd like users to have when running pulumi ai.

Fixes https://github.com/pulumi/pulumi.ai/issues/126

One question about subcommand vs. prompt. LGTM otherwise.

Are we still planning to rework this into a flag rather than subcommand?

[kpitzen]

I don't think so for this specific command, no. I wanted to keep the interface here as simple as possible, and making pulumi ai behave entirely differently between its future state (pprint/tui) and when --web --prompt 'some-ai-prompt' are provided feels... not ideal from a UX perspective. I'd rather we separate its interface from the above pulumi ai command. The other commands, like in org search are purely a boolean flag which doesn't modify the underlying interface so simply passing --web makes sense there.
