[envoy] Update internal WORKSPACE file (#14277)

envoyproxy/envoy#41894 updated Envoy's WORKSPACE
file, which caused the following oss-fuzz build error:
```
ERROR: Failed to load Starlark extension '@@bazel_features_version//:version.bzl'.
Cycle in the workspace file detected. This indicates that a repository is used prior to being defined.
The following chain of repository dependencies lead to the missing definition.
 - @@bazel_features_version
This could either mean you have to add the '@@bazel_features_version' repository with a statement like `http_archive` in your WORKSPACE file (note that transitive dependencies are not added automatically), or move an existing definition earlier in your WORKSPACE file.
ERROR: Error computing the main repository mapping: cycles detected during computation of main repo mapping
Computing main repo mapping:
ERROR:__main__:Building fuzzers failed.
```

This fix updates the WORKSPACE files, as is done in
envoyproxy/envoy#41894
