feat: Add verification details for some common crawlers

[e-moran]

This PR adds reverse dns verification details for common crawlers.

I chose to add verification as a list so that it can be present on all bots, regardless of whether we can verify or not.
When we add cidr validation in the future we will add it as a second option to those bots that support it, we can then just add logic to prefer cidr validation for bots that support both.

I think its nice to have both so that this JSON will show a full picture of everything that a crawler supports.

The mask can contain two types of wildcard:

• @ matches zero or more characters
• * matches zero or one character

By supporting both types of wildcard we can implement validation exactly how each bot provider specifies in their docs.

Few questions and things to double check
