add slug based on filename to ContentFile data

Which scope/s are relevant/related to the feature request?

content

Information

The slug for the URL of a content page (markdown) can currently be explicitely added using a frontmatter attribute or by extracting it form the filename which is part of the ContentFile interface. It would be neat it the slug can be provided by the content plugin based on the filename without removing manually the path and extension parts form the filename string.

Suggestion

export interface ContentFile< Attributes extends Record<string, any> = Record<string, any>> {
  filename: string;
+ slug: string;
  content?: string;
  attributes: Attributes;
}

Example

{
  attributes: { ... }
  filename: "/src/content/2023-foo-bar.md",
+ slug: "2023-foo-bar"
}

The slug should be URLEncoded.
