Issue: "panel.gitActions" option in view modes is not present in the JSON schema

[voltaney]

Describe the bug
In the following default JSON schema, panel.gitActions is not included in frontMatter.global.modes, and I got a validation error.
https://frontmatter.codes/frontmatter.schema.json

"features": {
  "type": "array",
  "default": [],
  "description": "The features you want to use for your mode.",
  "items": {
    "type": "string",
    "enum": [
      "panel.globalSettings",
      "panel.seo",
      "panel.actions",
      "panel.contentType",
      "panel.metadata",
      "panel.recentlyModified",
      "panel.otherActions",
      "dashboard.snippets.view",
      "dashboard.snippets.manage",
      "dashboard.data.view",
      "dashboard.taxonomy.view"
    ]
  }
