0.0.4

• Introduces a dedicated "markdoc" language identifier that is used instead of identifying Markdoc content as Markdown. This helps us avoid conflicts with Visual Studio Code's built-in Markdown language server. Note that this change requires users to either adopt a specialized file extension for Markdoc content (we support .markdoc, .markdoc.md, or .mdoc) or add a files.associations mapping for *.md files. Refer to the relevant section of the README for more details. (#4)
• Adds a selection range provider that supports using the shrink and expand selection feature to highlight Markdoc tag content (#3)
• Fixes a bug that resulted in invalid content ranges throwing errors for linked editing and other features when operating on a malformed document (#5)
