Lock web3 version to fix voter dapp

[mrice32]

web3 upgraded to a newer version of the Ethers abi coder/decoder. This caused calls in the dapp where we pass around large salts to fail to pass abi verification.

This fixes that issue by temporarily locking down the version of web3 to 1.2.7. This also required locking the version of web3 in the @umaprotocol/store drizzle package fork as well.

Glad this fix worked! Its probably worth referencing this outstanding issue about web3 1.2.28 so that it links back to that issue and to remind us why we locked at this version:

web3/web3.js#3544

Coverage remained the same at 92.73% when pulling 6f98098 on mrice32:fix_dapp into 4abe2d9 on UMAprotocol:master.
