Please publish 1.4.0 to BCR

Apologies, I do not currently have my employer's permission to do OSS contributions...

It looks like 1.4.0 is very friendly to Bazel, no patches are necessary. This is how I pull it but would be easier if it was in BCR directly:
```
bazel_dep(name = "highway", version = "1.4.0")
archive_override(
module_name = "highway",
urls = ["https://github.com/google/highway/releases/download/1.4.0/highway-1.4.0.tar.gz"],
integrity = "sha256-NvZyq0jds8hVXp6J4W/kAM19FsbrRVoaPQwUamOrq9w=",
strip_prefix = "highway-1.4.0",
)
```
