Install Subway from acala/subway:v0.1.1 Docker image; set 90s per-upstream timeout (#622)

* Install Subway from upstream `v0.1.0` musl release in `ci.yml`

Switches `cargo install --git` to a `curl | tar -xz` of the
released static binary
(https://github.com/AcalaNetwork/subway/releases/tag/v0.1.0,
published by AcalaNetwork/subway#202). Removes the Rust
toolchain install, Subway-HEAD commit-hash lookup, and
Swatinem cache layer that existed only to amortise the
`cargo install` cost — none of them have any other
consumer in this workflow.

* Install Subway from upstream `v0.1.0` musl release in `update-known-good.yml`

Same swap as the previous commit, applied to the periodic block-number
update workflow.

* Install Subway from upstream `v0.1.0` musl release in `update-snapshot.yml`

Same swap as the previous two commits, applied to the snapshot-update
workflow.

* Fail Subway download fast on HTTP errors (`curl -f`)

Without `-f`, an HTTP 4xx/5xx response (e.g. release deleted, GitHub
degraded) leaves `curl` exiting zero with the error body on stdout,
and the downstream `tar -xz` fails with a confusing "not in gzip
format" message instead. Per review on PR #622.

* Install Subway by extracting binary from `acala/subway:v0.1.1` Docker image

The `v0.1.1` GitHub Release at AcalaNetwork/subway is missing its
`x86_64-unknown-linux-musl.tar.gz` asset; the release workflow's
`Build release binary` step failed (`cargo build --locked` mismatched
the bumped `Cargo.toml` version), so the upload was skipped. The
upstream tag still produces a working Docker image because
`docker.yml` doesn't use `--locked`, so `acala/subway:v0.1.1` is
the only working consumption path for v0.1.1.

The image's binary lives at `/usr/local/bin/subway` (per Subway's
Dockerfile); copying it out with `docker create` + `docker cp` lands
in roughly the same wall time as the curl-and-untar path and unblocks
consumption of PR #203's `request_timeout_seconds` config field.

* Set Subway per-upstream `request_timeout_seconds` to 90s

Subway's default per-upstream request timeout is 30s. With three Acala
public RPC endpoints, heavy storage queries that take longer than 30s
cause Subway to cycle through all three endpoints (~90s) before any
single upstream has a chance to respond, and the test-side waiting
client times out.

`request_timeout_seconds` was added to `ClientConfig` in
AcalaNetwork/subway#203 (Subway v0.1.1+). Setting it to 90 lets a
single upstream attempt run long enough to complete those queries
instead of being preempted by Subway's own per-endpoint clock.

The companion exclusion of Acala tests in `vitest.config.mts` is
intentionally left in place; this commit only restores Subway's
ability to wait long enough. Lifting the exclusion is a separate
verification step.

* Re-enable Acala test suites

`request_timeout_seconds: 90` on Subway's upstream client (added to
`subway-template.yml` in the previous commit) gives Subway enough
time per upstream attempt for Acala storage queries to land before
the 30s default forced it to cycle endpoints. The exclusion added in
PR #621 is no longer needed and is removed; the exclusion comment is
narrowed to bifrostKusama, which still lacks a workable endpoint set.
