Bad error when missing a quote

[schneems]

This rundoc code:

:::-- rundoc.require "../shared/clean_ansi_spinners.md

Triggers this error:

## Cleaning tmp working directory, /var/folders/yr/yytf3z3n3q336f1tj2b2j0gw0000gn/T/d20241126-36078-tqwhmi
/Users/rschneeman/.gem/ruby/3.3.1/gems/rundoc-3.1.1/lib/rundoc/code_command/rundoc/require.rb:8:in `initialize': Path must be relative (i.e. start with `.` or `..`. "\"../shared/clean_ansi_spinners.md" does not (RuntimeError)

	from /Users/rschneeman/.gem/ruby/3.3.1/gems/rundoc-3.1.1/lib/rundoc/peg_parser.rb:210:in `block in <class:PegTransformer>'

The problem is not that it is not relative, but that it's missing a quote at the end.
