Go Bazel builds fail to find cel.dev/expr

[sfc-gh-randerson]

In #89 the cel.dev/expr based annotations were reintroduced. Unfortunately, there still seem to be issues when trying to use Bazel, Go and Gazelle together, and importing this module.

I've recently added a dependency on github.com/cncf/xds/go/xds/type/matcher/v3 and updated my dependency on go-control-plane to pick up a bugfix (envoyproxy/go-control-plane@77feb56 ).

(I'm not sure my new dependency there matters, tbh. It's just very close and maybe adding confusion.)

This update to go-control-plane updated the version to this library, and thus picked up the cel.dev/expr change.

Now, my builds fail with:
ERROR: /private/var/tmp/_bazel_randerson/01ba2733315bf63f62b0e43c3a981a72/external/com_github_cncf_xds_go/xds/type/v3/BUILD.bazel:3:11: no such target '@dev_cel_expr//:expr': target 'expr' not declared in package '' defined by /private/var/tmp/_bazel_randerson/01ba2733315bf63f62b0e43c3a981a72/external/dev_cel_expr/BUILD.bazel (Tip: use query "@dev_cel_expr//:*" to see all the targets in that package) and referenced by '@com_github_cncf_xds_go//xds/type/v3:type'

The BUILD file there doesn't actually define any go libraries, so this isn't particularly surprising, but I don't think this commit is working as expected right now.

I'm not really sure if the problem is here or in cel.dev/expr, but ... well, debugging 3 layers of modules down is not fun.

Lets see if we can poke folks to go accept google/cel-spec#379 and google/cel-spec#354

Not sure if it's related, but I can't build with bazel in WORKSPACE mode after upgrading to a recent commit.
