Remove Playwright from Renovate config (#1545)

# Pull Request

## 🤨 Rationale

[Milan pointed
out](#1542 (comment))
Renovate will fail to update Playwright because:
1. there is no Nuget version corresponding to the latest NPM version
2. there was a breaking change between 1.37 and 1.38

This will block automatic updates for all of our devDependencies.

## 👩‍💻 Implementation

1. Remove Playwright from the list of dev dependencies updated by
Renovate
2. Filed tech debt #1544 to address this

## 🧪 Testing

Once this goes in I'll inspect #1537 to ensure it no longer lists
Playwright
