[FR] End key to move cursor to end of a line

### Description

I really love AppFlowy, i customized it for my liking. I use it for note takings from PDF and Web, the issue i found coming from other editors is END key to go to the end of the line in a paragraph. Currently the end key takes cursor to end of line, i like to have Ctrl+End to take me to end of paragraph, and to go starting and ending of a page i can assign my page up and down keys. Please make this feature as assignable shortcut so users like me love to use and support AppFlowy

### Impact

This feature will be welcoming for new users and retention of existing one's
