[DEP] upgrade to latest version of @lexical (0.45.0) for mdx-editor

[alaa-paramount]

Hello,

I'm using both Lexical and mdx-editor libraries,
it would be great if we receive an upgrade to latest version of @lexical here so I won't have to use old version of lexical related packages:
"@lexical/list": "0.35.0",
"@lexical/react": "0.35.0",
"@lexical/utils": "0.35.0",
"lexical": "0.35.0",

instead of 0.45.0
