Potential fix for code scanning alert no. 15: Workflow does not contain permissions

[asmfstatoil]

Potential fix for https://github.com/equinor/neqsim/security/code-scanning/15

To fix the problem, you should explicitly set the minimal permissions that the workflow requires. The safest default is contents: read, which allows the workflow to read repository contents but not modify them, create releases, or write to issues/pull-requests. This fits the example and matches least-privilege principles. If in future the workflow needs broader permissions, you can expand them as needed. You should add the permissions: contents: read block at the root level (just after name: and before/after on: or above jobs:) of .github/workflows/maven_publish.yml.
