[chore][golangci-lint] Remove gosec excludes (#10411)

#### Description
The upstream issue was fixed by
golangci/golangci-lint#4748, which was included
in release
[`v1.59.0`](https://github.com/golangci/golangci-lint/releases/tag/v1.59.0)
of `golangci-lint`. From local testing, we're pulling version `v1.59.0`
of `golangci-lint`, so the issue should be resolved.

Local runtime with excludes:
```
$ .tools/golangci-lint run -v --enable-only gosec
...
INFO Execution took 1.866075148s
INFO Execution took 1.218805785s
INFO Execution took 1.09527985s
```
Local runtime without excludes:
```
$ .tools/golangci-lint run -v --enable-only gosec
...
INFO Execution took 2.244716429s
INFO Execution took 1.539717296s
INFO Execution took 1.530163777s
```

Note: I ran `.tools/golangci-lint cache clean` between each test to
clean the cache and keep results as consistent as possible.
