Move uvx to installation overview with correct command

Integrates uvx usage into the main installation overview text instead
of a separate subsection, and uses the correct command format.

Changes:
- Remove dedicated "Try it out" subsection
- Add uvx command to installation overview paragraph
- Use correct command format: uvx --from django-language-server djls serve
- Keep installation methods focused on persistent installs
