The rationale here is the following:
1) There are several "types" of RPC, that are supported or not by different providers - ETH, Filecoin and Archive API (which is basically more like how deep into chain may providers look, but if we look to the popular providers page - they always have Archive API as separate category)
2) I removed 2 providers - in the first one I was not able to query the node after all the registry procedures. Maybe I'm doing something wrong, but it basically simply throws me 404 all the time. For the second one - there are no information about them providing any FIL RPC at all.
3) I added dRPC instead as they provide publicly available API. I also verified with Chainlist that this works => https://chainlist.org/chain/314 and used benchmark tooling described in the doc to check providers response.
Updated calibnet RPC providers - made the same structure with mainnet just to make docs more clear for the end user. And fixed links for DRPC which where leading for mainnet actually instead of calibnet :)
