Protocol change to https style (And some markdown style updates)

[kotp]

First commit is for style consistency, second is actual helpful update to link.

• Style consistency
• URI Protocol Changes

It looks like the broken link was temporary, as it is working today.

Let me know if you still want the first patch.

@kotp Hi Victor! I guess you could use also link to Inria site resource: https://rmod-files.lille.inria.fr/FreeBooks/WithStyle/SmalltalkWithStyle.pdf, but I'm not sure, which one is more reliable (probably webarchive)?

I suppose I could, but would rather link to the live version if it is stable, since any updates the author would wish to make we would gain the benefit of.

The updated link has been restored, but the http secure protocol has been updated for pharo.org links.
