docs: demonstrate JavaScript heap setting

[MarArMar]

Error prevented described here : actions/runner-images#70

Note: This "heap out of memory" error happened on BOTH github actions & Netlify,

In BOTH cases the error was solved with this

(In Netlify I had to manually set the environment variable)

It was with a Sveltekit project that was a landing page,

When built, the build folder was only 29 files & 935 kb

So I expect other to experience the error as well.

Please don't delete this checklist! Before submitting the PR, please make sure you do the following:

• It's really useful if your PR references an issue where it is discussed ahead of time. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs
• This message body should clearly illustrate what problems it solves.
• Ideally, include a test that fails without this PR but passes with it.

Tests

• Run the tests with pnpm test and lint the project with pnpm lint and pnpm check

Changesets

• If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running pnpm changeset and following the prompts. Changesets that add features should be minor and those that fix bugs should be patch. Please prefix changeset messages with feat:, fix:, or chore:.

if we do add this then we'd need to add some description about why. i'd suggest to comment it out in the docs since we don't know that 4096 is optimal for everyone as we don't know the size of their runner, whether they're hitting the issue, etc.

Suggested change

	NODE_OPTIONS: '--max-old-space-size=4096'
	# you can increase the memory allocated to the heap if you run out of memory while building
	# https://github.com/vitejs/vite/issues/2433
	# NODE_OPTIONS: '--max-old-space-size=4096'

Ok

This doesn't feel right to me. If we add it to the adapter-static docs then we also need to add it to the adapter-node, adapter-cloudflare, adapter-cloudflare-workers, adapter-netlify docs, etc. If we want to add it, then probably the FAQ would be a better location

I'm going to go ahead and close this for the reasons described in the last comment. I think it's relatively easy to find the solution already and adding it just in this one place would create an inconsistency with our other docs
