CODEOWNERS: Reduce go.mod/go.sum related pings

[felixge]

What does this PR do?

• Remove @DataDog/dd-trace-go-guild as the CODEOWNER for go.mod and go.sum.

Motivation

Most PRs that touch go.mod or go.sum are only relevant for the team working on it. For example: #2410

This change will avoid the @DataDog/dd-trace-go-guild team to be added to such PRs by default and allow anybody with review permissions on dd-trace-go to approve the PR.

Reviewer's Checklist

• Changed code has unit tests for its functionality at or near 100% coverage.
• System-Tests covering this feature have been added and enabled with the va.b.c-dev version tag.
• There is a benchmark for any new code, or changes to existing code.
• If this interacts with the agent in a new way, a system test has been added.
• Add an appropriate team label so this PR gets put in the right place for the release notes.

For Datadog employees:

• If this PR touches code that handles credentials of any kind, such as Datadog API keys, I've requested a review from @DataDog/security-design-and-guidance.
• This PR doesn't touch any of that.
