feat: arbitrum eips diffs

[leovct]

Related to #37.
Requires #59 to be merged (and to rebase this PR).

Add Arbitrum EIPs diffs. Just like Optimism diffs (#53), it adds diffs for EIP-1599 and EIP-4399 (PREVRANDAO).
@mds1 Not sure about EIP-4895 (withdrawals lists)?

Also fix a url formatting issue.

Hey @gzeoneth, could you help us with some Arbitrum EIP information? Context is listing which mainnet EIPs are implemented, and what parameter differences there may be from mainnet. We're only listing execution related EIPs, no consensus, networking, etc. EIPs.

For example, here's what it looks like for Optimism‚the same EIPs are implemented, but with a few differences explained in the "Notes" section of each row: https://www.evmdiff.com/diff?base=1&target=10#eips

Hoping to get something similar for Arbitrum. I assume all EIPs are implemented, with the following exceptions:

• No EIP-1559: A similar approach is used. Are there parameters we should use reference here? Any references you might have showing how it's equivalent would also be great.
• EIP-4399: Just returns the constant 1
• EIP-4895: Does arbitrum have an empty withdrawal list similar to Optimism?

Thanks!

• EIP-1559: partially implemented with the following exception
  • target a gas per second ("speed limit") instead of block gas limit to account for the variable block time in Arbitrum
  • priority fee is not collected by the network even when nonzero value is specified
• EIP-4399: Always returns 1
• EIP-4895: Arbitrum currently do not generate block with withdrawalsRoot

Let me also circulate to my team to see if anything is missing
