[hjpotter92]

What does this pull request do? Explain your changes. (required)

Minor change (following up from #2196) to the livepeer-data/pkg/mistconnector package.

Specific updates (required)

• Bump version from 0.4.8 to 0.4.11 which fixes the falsely reported boolean flag for integer values.

How did you test each of these updates (required)

Generated a binary locally, and tested with the falsy reported flag value:

  "maxGasPrice": {
    "name": "maxGasPrice",
    "help": "Maximum gas price (priority fee + base fee) for ETH transactions in wei, 40 Gwei = 40000000000",
    "option": "-maxGasPrice",
    "default": "0",
    "type": "uint"
  },
  "maxPricePerUnit": {
    "name": "maxPricePerUnit",
    "help": "The maximum transcoding price (in wei) per 'pixelsPerUnit' a broadcaster is willing to accept. If not set explicitly, broadcaster is willing to accept ANY price",
    "option": "-maxPricePerUnit",
    "default": "0",
    "type": "uint"
  },

earlier, both those flags were reported as bool
