Update to work on Node LTS

[allmarkedup]

Addresses the issues discussed in #17.

I tried running @LewisDaleUK's PR (#14) which attempts the same thing but had a few issues for me (bundle size and timeouts).

As in the previous PR this updates puppeteer-core and replaces chrome-aws-lambda with @sparticuz/chromium and additionally:

• Configures the function to treat @sparticuz/chromium as an external module (see [BUG] Error: ENOENT: no such file or directory, open '/var/bin/chromium.br' Sparticuz/chromium#24 (comment))
• Adds some extra logic to ensure that Chromium correctly closes all pages and always shuts down the browser (see https://github.com/Sparticuz/chromium?tab=readme-ov-file#im-experiencing-timeouts-or-failures-closing-chromium)

Which from my testing fixes the bundle size and other issues in #14.

Thank you! The code changes were a little noisy so I merged some of the changes externally.

Note also the comment here as the production service is now running on Vercel: #14 (comment)

I’d consider this v1-netlify branch to be deprecated but I’m happy to continue merging PRs to it if folks want to help maintain it.

Sounds good! Thanks for your work on this @zachleat.
