Add hatch installation option with uvx

[eugengi]

Description

uv has grown to have a large community and rapid adoption. This PR introduces a minor patch to the install docs to inform users of an optional Hatch installation with uv. Users, or anyone managing isolated tools with uv, can now install Hatch in a persistent, isolated, globally available environment.

Decisions

This section outlines notable considerations for developers/maintainers.

• uvx (an alias for uv tool run <tool>) executes tools in a temporary, cached virtual environment.
• uv tool run <tool> installs tools in a persistent, isolated, global environment, similar to pipx.
