Turns out people use templating languages and interpolation in frontmatter which makes it invalid unless rendered first. The idea of this PR is to pass-thru frontmatter when attempts to parsing it fail.

Fixes stateful/vscode-runme#1455

Lemme know what you think @adambabik. Making checking for errors optional seemed like the best way forward to solve for the PR's description/linked issue.

I think the solution makes sense. I added a few comments on how the public APIs can be improved.

Suggestion: as this interface will likely get extended, I suggest this:

Suggestion: Let's stick with Frontmatter for consistency.

Suggestion: We can have two methods: Frontmatter() *Frontmatter and FrontmatterWithError() (*Frontmatter, error). I think it will be a bit more clear and the caller will only need to use one method when it wants to handle frontmatter's error.

Suggested change
func (d *Document) FrontmatterError() error {

Remark: With my earlier suggestion, this will become:

Suggested change
notebook, err := editor.Deserialize(logger, data, identityResolver)
notebook, err := editor.Deserialize(data, editor.Options{IdentityResolver: identityResolver})

The logger can be figure out by editor.Deserialize and default to noop.
