Replace the images of step by step migration using new migration app

Nice to have the ability to enlarge the image, especially in mobile

May need to save multiple formats of image

Document states (n = 2h) which obviously should be n=2^h.

Thanks discord user @Breus#1005 for pointing this out!

The latest release of QRL changed the mining address flag from --miningCreditWallet to --miningAddress.

FInd and kill any spelling errors, punctuation, and rewording that is needed in the documentation

Epic for adding better API documentation to the site. Give examples of API use in multiple languages.

In order for QRL to reach the legitimate state of cryptocurrency, I thought that we needed a symbol for QRL unicode. In my opinion, the symbol can be shaped by combining binary numbers 0 and 1. The logo symbolizes quantum superposition state which simultaneously works as both 0 and 1.

Here's the sample for QRL unicode symbol ('shor' unit) that I've designed:

e.g. https://en.bitcoin.it/wiki/Bitcoin_symbol

Update the first command "Install QRL Node and dependencies" from:
docker pull qrledger/qrl-docker
to
docker pull qrledger/qrl-docker:bionic

Adding documentation for the upcoming token migration phase.

When using headers in the documentation header 3 highlights blue with an underline

Can we remove the blue and underline

In the Ledger Nano S documentation page https://docs.theqrl.org/wallet/ledger-nano-s/
it reads "Ledger Nano S Initialising QRL App", should be "Ledger Nano S Initializing QRL App"

Further down on step 4. It says "Scroll down and press both buttons on the Init Device menu option." should be "Scroll down and press both buttons on the Init Tree menu option." as it shows on the ledger Nano S device

Note. This occurred on a new device setup today.
