Updates to Swapr after DXdao dissolution

[0xVenky]

Update the Landing page items: What do we do with this? - Remove?

Remove the roadmap section - pretty old

Remove this section as well as it is just redundant info from the footer

We need to make some decisions on this:

• we need a new FAQ that has some basic questions
• we should update the brand assets and have it with us, check with Keenan / Zett.
• Update the new discord
• Keybase?? remove ?
• Forum? - need to decide which is the new place for forum.
• Redo everything under documentation and see how much relevant they are
