[Security Solution] Update CODEOWNERS for the Security Engineering Pr…

…oductivity team (#170662)

## Summary

This PR makes the @elastic/security-engineering-productivity team the
owner of the `x-pack/test/security_solution_cypress/package.json` file
to prevent accidentally merging temporary changes to this file like in
#169182.

Also, it simplifies the ownership rules a bit. The following lines
assign the team to all files under the two specified folders, but not
files inside their subfolders, so you don't have to specify individual
files:

```
/x-pack/test/security_solution_cypress/* @elastic/security-engineering-productivity
/x-pack/test/security_solution_cypress/cypress/* @elastic/security-engineering-productivity
```
