Adding a dropdown box for resources section in the nav-bar

1. Adding a dropdown box to collect all the resources offered in the schema server.
2. Removing the old guidelines page, adding references to the Understanding OCSF doc and Contribution guide.

Taking a look. Going to try the gh tool to check out the PR and play around with the new feature a bit.

Tested out locally from various views, working as expected.

Looks good to me

I approved, however I'd like to suggest a change, and if you agree, perhaps implement it with this PR.

Edit: We need to bump the version, so I changed the approval to a change request. The bit below remains a suggestion to consider.

Of the 4 items in the "Resources" dropdown, 3 are links that open a new page, however "Data Types" navigates the schema browser to the its own "Data Types" page. I can see why it was done this, way, however I think "Data Types" should be moved to a sibling of the other top level navigation items. Something like this:

Categories   Classes   Base Event   Dictionary   Objects   Data Types   |   Resources

Version needs to be bumped from 2.60.0 to 2.61.0 in the top level mix.exs file.

Ah the version number, pushed a commit for that. About the the dropdown - Yeah I had initially considered the same style, but later arrived at this since Data Type really fits as a resource for the framework. But I am not married to that idea, I would be okay either way.

Approved. In the interest of time, let's live with this for a bit and decide later if "Data Types" should be moved.
