fix: formatting issues on tiptap editor

[prathameshkurunkar7]

As per the issues mentioned above, here are the changes made:

Solutions:

1. Added support for Inline Code, another button which lets you add inline code and render's it similarly.
2. Code Block takes up entire text instead of the current line is fixed by allowing Shift + Enter to add soft line breaks, which would make the node as separate paragraph tags which in turn allows us to add code block to particular line instead of entire text block. Moreover discovered that 3 times press Enter inside CodeBlock would allow us to escape it as well.
3. Link was extensible but fixed it by referring to the solution mentioned in the thread. After inserting the link, all words are also part of the link ueberdosis/tiptap#2571
4. Upgraded the TipTap packages to latest version.

Also close #733 as it was solved earlier.
