Custom relationship field view not resolving in Admin UI build

When trying to use a custom view for a relationship field in the Admin UI, the build process fails due to a module resolution error. The custom view file is not being correctly resolved during the Next.js build process that Keystone uses for the Admin UI. it works in development mode.

create a custom view, and use it in the schema
like example https://github.com/keystonejs/keystone/blob/main/examples/custom-field-view/schema.ts#L27
```
agent: relationship({
ui: {
labelField: "identityCode",
displayMode: "select",
views: "../components/FilteredRelationship.tsx",

```

it shold build without any error

here is package.json

```
"dependencies": {
"@keystone-6/auth": "^7.0.0",
"@keystone-6/core": "^5.0.0",
"@keystone-6/document-renderer": "^1.1.2",
"@keystone-6/fields-document": "^7.0.0",
"react-infinite-scroll-component": "^6.1.0",
"slate": "^0.103.0",
"slate-history": "^0.100.0",
"slate-react": "^0.107.1",
"typescript": "^4.9.5",
"uuid": "^10.0.0"
}

```

Start with examples/custom-field-view/schema.ts and the referenced custom view path, then trace the Admin UI Next.js build and its module-resolution error. Reproduce the build using the relationship field configuration; done means the custom relationship view resolves and the build completes without an error.
