feat: use edge-light condition when building for Vercel Edge Runtime

[blaine-arcjet]

This adds the edge-light condition to the esbuild.build() command used to bundle code for Vercel's Edge Runtime. I noticed that the condition wasn't respected when marking some dependencies as ssr.external even though the packages supported Edge Runtime via the edge-light condition.

This change brings the compilation more in line with Next.js, as it leverages the edge-light condition.

Adding the conditions configuration also requires manually adding module because it is only defaulted if nothing is configured.

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.
  - I didn't see any tests for the adapters.

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:.

Edits

• Please ensure that 'Allow edits from maintainers' is checked. PRs without this option may be closed.
