Implement Hono SDK

[smeubank]

We want to implement @sentry/hono with full support for that framework.

Some other information about hono and Sentry:

• Sentry Middleware for Hono, based on 3rd party toucan SDK for cloudflare: https://www.npmjs.com/package/@hono/sentry?activeTab=readme
  • related PR: Add Sentry integration for Hono #12424
  • https://hono.dev/docs/guides/middleware#third-party-middleware
  • https://hono.dev/docs/middleware/third-party#others

Just for context: Third-party docs for hono are already mentioned here https://docs.sentry.io/platforms/#sdks-supported-by-our-community

and about hono + cloudflare workers?
I tried

app.use('*', async (c: Context, next) => {
  console.log('Environment:', getEnvVar('ENVIRONMENT', c.env));
  console.log('Sentry DSN:', getEnvVar('SENTRY_DSN', c.env));

  sentry({dsn: getEnvVar('SENTRY_DSN', c.env), environment: getEnvVar('ENVIRONMENT', c.env)});

  const { db } = initializeDb(c.env as { DB_URL: string });
  c.set('db', db);
  c.set('env', c.env);
  await next();
});

but no errors or transactions are being captured ( locally via deno start )

We're currently working on a guide for Hono getsentry/sentry-docs#12710. With this PR we'll add setup docs that mention Cloudflare specifically. Here's a link to a preview page (warning: this might not be the final version that goes into our official docs)

@Lms24 does cloudflare handle the source maps or do you use tsc? Wasn't clear from docs as you don't typically use a build script with cloudflare workers.
