feat(astro): add tunnelRoute option (#10309)

[florian-lefebvre]

Closes #10309

• If you've added code that should be tested, please add tests.
• Ensure your code lints and the test suite passes (yarn lint) & (yarn test).

I have not added tests just yet because I don't know how to mock virtual imports. I'm waiting for an answer from the Astro Discord.

Do you have something like changesets? Couldn't find it

@florian-lefebvre we handwrite our changelogs since we rely on gitflow + our release tool craft - feel free to open up the PR we'll take care of the changelog!

Hey @florian-lefebvre thanks for opening this PR! I only skimmed it as I don't have much time at the moment but will take a closer look hopefully tomorrow. Nice idea with the virtualized config module!

I ran CI and looks like there are some build issues in the Astro package. Are you able to reproduce this locally?

[florian-lefebvre]

A few reasons, but idk how to fix them:

1. [tunnel.ts] Globals are not recognized: fetch, URL, Response, Request
2. [virtual.d.ts] Looks like the type import does not work
3. [virtual-imports.ts] Not sure how to fix eslint errors

Regarding testing, there's something about virtual modules (see docs). I've almost never tested Astro/integration code before so I'm not sure what's the best approach here

I'll close this PR as part of a larger issue and PR cleanup throughout the Sentry repo. Sorry for not getting back to you back then, unfortunately, priorities didn't align well. I think this is a nice feature but it would need some more refinement to ship this. Let me know if you want to give this another shot. Happy to reopen :)
