gazelle resolve directives not working

### What version of gazelle are you using?
0.35.0 (bazel-gazelle)

### What version of rules_go are you using?
0.44.0

### What version of Bazel are you using?
6.4.0

### Does this issue reproduce with the latest releases of all the above?
Yes (currently using latest versions).

### What operating system and processor architecture are you using?
Ubuntu 20.04, x86_64

### Any other potentially useful information about your toolchain?
Using GO version 1.20.3

### What did you do?
Created a minimalistic bazel repo (https://github.com/VhalPurohit/gazelle-go-bug/tree/master) for a single main.go file that imports `"cloud.google.com/go/storage"`
its build rule has `deps = ["@com_google_cloud_go//storage"]` with a directive `# gazelle:resolve go google.golang.org/genproto/googleapis/iam/v1 @org_golang_google_genproto//googleapis/iam/v1
` and the build has a `go_repository` rule defined as such
```
go_repository(
name = "com_google_cloud_go",
build_file_proto_mode = "disable_global",
build_directives = [
"gazelle:resolve go google.golang.org/genproto/googleapis/iam/v1 @org_golang_google_genproto//googleapis/iam/v1", # keep
],
importpath = "cloud.google.com/go",
strip_prefix = "google-cloud-go-storage-v1.36.0",
build_file_generation = "on",
urls = ["https://github.com/googleapis/google-cloud-go/archive/storage/v1.36.0.zip"],
)
```
this repository rule by itself doesn't work so I kept adding go_repositories that `@com_google_cloud_go` depends on unitl the missing strict dependencies error that I couldn't get around

### What did you expect to see?
`bazel build t2:main` succeeds (there are explicit gazelle resolve directives both in the go_repository rule and the BUILD file to prevent the missing strict deps error)

### What did you see instead?
❯ bazel build t2:main

### Comments
The import that causes the failing strict dep is a protobuf import `pb "google.golang.org/genproto/googleapis/iam/v1"
` in com_google_cloud_go/iam/iam.go ; so I tried the `go_repository` rule with all of
1. `build_file_proto_mode = "disable_global"`
2. `build_file_proto_mode = "disable"`
3. `build_file_proto_mode = "default"`
4. removing the `build_file_proto_mode` attribute altogether.

But all of them lead to the same error.
It seems like the build directives are not working, but I don't really know what's going on to be fully honest. Please help.

Start with the linked minimal repository, its main.go, the generated external/com_google_cloud_go/iam/BUILD.bazel, and the go_repository build_directives. Run bazel build t2:main and inspect how the gazelle:resolve directive is applied to the google.golang.org/genproto/googleapis/iam/v1 import. Done means the strict-dependencies error is resolved without adding unsupported repository declarations.
