fix(docs-infra): temporary SW fix (for online mode) (#25692)
fix(docs-infra): temporary SW fix (for online mode) (#25692)

Due to unknown reasons, Firebase seems to return a 301 response for
`/index.html`, but without a `Location` header. According to the spec,
the browser will not follow the redirect, considering the response as
failed, instead.

This commit temporarily removes `index.html` from hashed resources and
changes `index` to `/` in `ngsw-config.json`, until we figure out an
appropriate long-term solution.
