fix(ci): repair wrapped ENABLE_ANALYTICS expression in deploy-docs workflow (#9271)

* fix(ci): repair wrapped ENABLE_ANALYTICS expression in deploy-docs workflow

The `${{ ... }}` expression for ENABLE_ANALYTICS was wrapped across two
lines (splitting mid-expression after `||`), producing a YAML syntax
error. Join it back onto a single line.

* fix(docs): remove broken anchor link to aside in fp8-storage page

The link to #for-full-precision-models-only targeted a Starlight
:::caution callout, which doesn't generate a heading anchor. This
failed starlight-links-validator and broke the docs build. Drop the
anchor link, keep the cross-reference prose.
