feat: add windows cmd & powershell init scripts

Closes #1008

Screenshot of the end result:

Notes

Also changed the "Start the IPFS daemon" text to match one common use case:

• User has already started daemon, but didn't setup the headers. After setting up the headers, the user is confused why it's not working. Maybe reading the "restart daemon" will help.

This is great 😊 Just one tiny text suggestion. Thanks!

After discussing with @jessicaschilling, we came with this simple way to further help the user differentiate between which OS bash commands to use: https://i.imgur.com/nJ8JRhL.png

LGTM, but we should be good citizens and credit icon authors/sources
(eg. in JS comments)

Tux (linux mascot) can be freely used:

• https://www.wired.com/2001/03/the-story-behind-tux-the-penguin/:

  On his website, Ewing grants everyone permission to use and modify the Tux image as they see fit, but he requests that he and GIMP be given credit "if someone asks."

I am not sure what is the license / source / status for the rest of icons used in this PR.

[jessicaschilling]

Actually ... this probably isn't going to work.
Apple icon is likely a no-go per: https://www.apple.com/legal/intellectual-property/guidelinesfor3rdparties.html
Microsoft rules are similar: https://www.microsoft.com/en-us/legal/intellectualproperty/trademarks/usage/general.aspx

Sad, but best to be cautious. Thanks @lidel for flagging.

[rafaelramalho19]

Thanks for looking into that. I reverted the icon changes then 👍
