Describe the bug
When creating an incident where the name of the affected system(s) contains a whitespace or comma, NetlifyCMS' list widget doesnt allow the user to enter these two characters

Reproduction steps
Steps to reproduce the behavior:

1. Create a system component that has a space or comma in it (e.g. "example.com website")
2. Create an incident and try to type in the system component's exact name

Expected behavior
Spaces and commas should be allowed within a system component name

Additional context
Partial-Workaround:

1. Type the text first then add the spaces - example.comwebsite -> example.com website

Possible solution:

1. Replace static/admin/config.yml lines 62-65 with:
   - { label: "Affected systems (use exact name, separated by commas) 🧐", name: "affected", widget: "list", required: false, summary: "{{fields.individualaffected}}", field: { label: "Affected System", name: "individualaffected", widget: "string" }}
   (sorry, I'm new at contributing, not sure how to directly reference the code in the file)

2. Use a select widget instead of list and populate select widget options with system components defined in repo-root/config.yml
