Joshenlim/fe 4445 explorer export as pdf option 2 (#50786)

## Context

Another take on [this
PR](https://github.com/supabase/supabase/pull/50733), decided that it's
better UX + DX to use a PDF library (`@react-pdf/renderer`) instead for
handling exporting Notebooks to PDF. The previous method using `print`
involved a lot of sparse patching in various places + had a lot of
limitations, not to mention its awkward UX to "Print".

There's a lot of code changes in this PR but it's because we're
constructing the PDF document based on the notebook's contents using
primitives from `@react-pdf/renderer` which gives us a lot more control
over the PDF's output.

PDF output will differ slightly from the Notebook UI in the browser
- Added a custom header in the report which covers the notebook name +
project name, and when its exported
- Empty markdown cells are skipped
- Query cells will show both SQL content + results (either table or
chart)
- Opting to skip syntax highlighting for SQL content (Can consider
separately)
- Results will only be included in the PDF if the notebook's been run
(Aligns with Copy as Markdown CTA)
- For table results, _all_ rows will be rendered (Aligns with Copy as
Markdown CTA)

Feel free to give it a spin! 🙂 🙏
