vale: ignore shortcodes inside markdown links via BlockIgnores

The previous TokenIgnores pattern only caught isolated shortcodes
and couldn't handle markdown links whose text or URL contained a
shortcode, because TokenIgnores can't span multiple tokens. Moving
that pattern into BlockIgnores lets it match across whitespace.

Also widen the inner pattern from `{{[%<]…[%>]}}` to `{{[^}]+}}` so
Go template actions (`{{- $url := … }}`, `{{ .Content }}`) inside
.inline shortcode blocks are ignored too. Fixes spurious URL/term
hits in the engine/install pages and the docker-agent examples.
