feat(core): added preserving and managing original markdown formatting for YfmTable

[makhnatkin]

Fixes #557

Enhancements in the Markdown Parser and Serializer

1. Dynamic Modifiers
   Dynamic modifiers have been added to the parser MarkdownParser and serializer MarkdownSerializer to enable flexible token, attribute, and node modifications. The changes follow SOLID principles and maintain backward compatibility.

   Change diagram: illustrates the integration points of the modifiers.

   

2. New Modifier Classes
   Introduced classes: MarkdownParserDynamicModifier and MarkdownSerializerDynamicModifier. They support configurations with composite keys, allowing shared handlers for different element types.

   Example:

     'paragraph,heading': /* fn */,
     paragraph: /* fn */,

3. ExtensionsManager Update
   The ExtensionsManager has been modified to pass dynamic modifiers to the parser and serializer, enabling their automatic integration and processing.

4. Preserving Raw Markup in yfm_table
   Configurations for dynamic modifiers and a markup manager have been added to ensure proper preservation and restoration of table contents.

5. Content Hashing for Raw Markup
   Introduced classes: MarkupManager.The markup manager uses content hashing (UUID v5) to store and accurately restore raw markup during serialization.
