Add back links to Uniswap Tutorial page

[critesjosh]

These pages were marked as draft in the front matter to exclude them from being built in the docs. This broke all of the associated links. When these pages get added back to the docs, we should add the links back in (be reverting the associated commits)

[jzaki]

Revert either of these to bring back the drafted docs and references:

• Accounts
• Uniswap

EDIT: added patches in case github purges squashed commits:

• hide-accounts-commit-a687fbe62.zip
• hide-uniswap-commit-5173c0f2f.zip

Account contracts page was added back
