Support id mode. Add files-metadata input

Description

Added

• feat: Add files-metadata input. It allows the user to provide a JSON array with the metadata of the files to be synchronized. This way, the user can set the Confluence id, title, etc. without the need to add frontmatter to the markdown files.
• feat: Support id mode. It allows the user to provide a list of files to be synchronized only by their Confluence id.

Changed

• chore(deps): Bump @tid-xcut/markdown-confluence-sync from 1.0.0 to 1.1.0 (Add id mode and filesMetadata option)
