Package ID should have correct capitalization

Summary

When adding connectors, the package id should have the correct capitalization, otherwise the connector fails to load.

Steps to reproduce

EDR v0.9.1, run:

PS > .\edr.exe connector add reductech.edr.connectors.pwsh
PS > .\edr.exe run scl "PwshRunScript 'Write-Host hello'"

Current Behavior

2021/06/03 11:55:17.632 ERROR Failed to load connector configuration 'reductech.edr.connectors.pwsh' from 'D:\dev\Reductech\EDR\edr\publish\connectors\reductech.edr.connectors.pwsh\0.9.1'.

Expected Behaviour

No error, prints 'hello'.

Suggested Fix(es)

This is the entry in the connectors.json:

  "reductech.edr.connectors.pwsh": {
    "id": "reductech.edr.connectors.pwsh",

The ID should have the correct capitalization.
