fixes commit SHA in docs/go.sum

[jputrino]

Proposed changes

• The release tag for nginx-hugo-theme v0.37.0 was deleted and re-created, which caused hugo to return a security error when downloading the theme. Because I know the DocOps team deleted and re-created the release, I replaced the old SHA in the go.sum file with the correct, newer one to resolve the issue.
