Issue:
Get warning, if I try to configure `post_template` with `needs_global_options`
if I try to configure `post_template` with `needs_global_options`, I do get following Warning:
`WARNING: needs_global_options 'post_template' must also exist in needs_extra_options, needs_extra_links, or ['constraints', 'layout', 'status', 'style', 'tags']`

I believe `NeedsCoreFields` in `sphinx_needs.data` is to [restricted](https://github.com/useblocks/sphinx-needs/blob/490603d833bafcd87383ec2de88fab0066b01558/sphinx_needs/data.py#L83C1-L83C16).

I would want to change at least the options: collapse, hide, template, pre_template, post_template, type_color, type_style

My workaround in `conf.py`
```
from sphinx_needs.data import NeedsCoreFields
patched_options = [
    ('collapse', 'bool'), ('hide', 'bool'),
    ('template', 'str'), ('pre_template', 'str'), ('post_template', 'str'),
    ('type_color', 'str'), ('type_style', 'str'),
]

for po_name, po_type in patched_options:
    NeedsCoreFields[po_name]["allow_default"] = po_type
```

Pull request description:
🔧 Allow pre/post template `global_options`
Even though these template are an awful design decision in sphinx-needs (hint, you don't jinja when you have a fully expressive restructuredtext syntax), let's add them back in for now for back-compatibility
