chore(sdk) [NET-1452]: Optimize ABI JSON files (#3079)

Optimized SDK bundle size by converting contract ABI JSONs from `json`
format to `full` format
(https://docs.ethers.org/v6/api/abi/abi-coder/#FormatType).

The full `format` is more compact than the `json` format. As we use
named parameters in events (e.g. `deploySponsorshipContract()`) and
structs (e.g. `convertChainPermissionsToStreamPermissions()`) we can't
use the `minimal` format.

## Statistics

The `streamr-sdk.web.min.js` bundle decreased  67k in size.

## Conversion

These ABIs are converted from the full format ABIs by running this
script:

```ts
import fs from 'fs'
import { Interface } from 'ethers'

const filePath = process.argv[2]
const rawAbi = JSON.parse(fs.readFileSync(filePath))
const iface = new Interface(rawAbi)
const formattedAbi = Object.values(iface.fragments).map(fragment => {
    // use full format so that we can use named event parameters
    return fragment.format('full')
})
fs.writeFileSync(filePath, JSON.stringify(formattedAbi, undefined, 4))
```
