Cardano Updates

I recently uploaded my personal cheatsheet on my staking pool's GitHub repository to help other staking pool operators to quickly setup a Cardano node using CNTools. This guide includes useful commands to enhance security and stability with 2FA, SSH, Firewall rules, backups with snapshots, synchronization, IP banning, etc. I also configured simple navigation links to improve the user experience when going through the guide. This might be specially interesting for SPOs who seek to reduce operation costs or to improve their decentralization by migrating their Cardano nodes to private servers or to smaller and more local data centers. We know that this process normally requires to setup the nodes from scratch and most guides aren't quite summarized. I hope the community considers this resource to be included in the staking pool section of the developer portal.

`export PATH="~/.local/bin/:$PATH"` didn't work with me on Mac OSX 11.5.2 running zshrc, since my .zshrc didn't recognize `~` as $HOME. Instead, it worked with `export PATH="$HOME/.local/bin/:$PATH"` which I believe should work for others as well.

An alternative update to instructions could be to specify that `export PATH="$HOME/.local/bin/:$PATH"` could work if `export PATH="~/.local/bin/:$PATH"` does not.

So it saves time for anyone debugging why running `cardano-cli --version` doesn't work.

The text speaks of 10k blocks, but the code of 10k slots, those are different things, so I've corrected the text to align with the code.

You sign with payment key and policy key, so I guess the witness count should be 2 for those transactions instead of 1?

* Removing the random constraint for building wallet (#297)

Building the wallet with `--constraint="random<1.2"` results in:

```
Building library for cardano-wallet-core-2021.9.9..

    Could not load module ‘System.Random.Internal’
    It is a member of the hidden package ‘random-1.2.0’.
    Perhaps you need to add ‘random’ to the build-depends in your .cabal file.
    Use -v (or `:set -v` in ghci) to see a list of the files searched for.

```

Issue here: https://github.com/input-output-hk/cardano-wallet/issues/2824
Raising this PR to discuss as I don't understand the significance of removing the constraint.
