fix(ci): adoption-smokes workflow YAML — quote step name with colon

The Astro step's name was unquoted: `Astro adoption smoke (target: lit
+ Vite plugin slot)`. The unquoted `: ` inside the name confuses YAML's
parser into thinking it's a map key separator — the workflow file
failed parsing entirely, surfacing as "X This run likely failed
because of a workflow file issue" in the Actions UI (0-second
duration).

Fix is a quoted double-quote string + swap `target: 'lit'` → `target='lit'`
to keep the syntax safe even if the surrounding quoting changes in
future. Validated locally with js-yaml — the file now parses to the
expected 8 steps.

Same trap would also bite the docs Astro page if a code block referenced
the YAML config without an explicit `target='lit'` form — leaving the
docs as-is since their target is `'lit'` (a quoted string in JS/TS
context, where the colon is a property separator, not a YAML map
delimiter).
