feat(apollo-react): add remark-breaks to sticky note markdown rendering, scroll improvements (3/3) [MST-7636]

[david-rios-uipath]

There are two main changes in this PR:

• Line break rendering support
• Simpler scrolling on overflow

1. Line break rendering support

Adds remark-breaks (remark plugin) to turn soft line endings (enters) into hard breaks. This makes our line end behavior fall more closely in line with what a user would expect from a WYSIWYG editor (i.e. FigJam sticky notes)

Before

After

2. Simpler scrolling on overflow

Only adds nowheel class to the sticky note element when the wheel event starts on the sticky note. This prevents the sudden cancellation of canvas scroll inertia (e.g. if the user starts scrolling outside the sticky note and their cursor ends up within the sticky note, we continue navigating on the canvas and ignore sticky note scroll behavior).

Before

User has to manually drag the scrollbar to scroll on a sticky note w/ overflow
