Documentation Suggestion: anchor links on ECS fields

[gimmic]

This is really pretty simple and I'm not sure where else to properly capture it.

The existing ECS documentation should have anchor tags on each field name in the ECS guide so you can easily deep-link directly to the relevant field.

When collaborating, often I'll say "Look at this field(such as rule.id)". I can link the fields category page, but I can't deep-link directly to the field of discussion.

Just a small quality of life change that could speed up collaboration.
