fix(integrations): Do not use convenience decorator

[sentrivana]

Quick fix for #3021. Removing the decorator gets rid of the issue.

We should follow up and fix the decorator later, e.g. here: #2892

Closes #3021

General Notes

Thank you for contributing to sentry-python!

Please add tests to validate your changes, and lint your code using tox -e linters.

Running the test suite on your PR might require maintainer approval. Some tests (AWS Lambda) additionally require a maintainer to add a special label to run and will fail if the label is not present.

For maintainers

Sensitive test suites require maintainer review to ensure that tests do not compromise our secrets. This review must be repeated after any code revisions.

Before running sensitive test suites, please carefully check the PR. Then, apply the Trigger: tests using secrets label. The label will be removed after any code changes to enforce our policy requiring maintainers to review all code revisions before running sensitive tests.

Would be good to add a test for whatever behavior the user observed in the issue. Can wait to be done in a separate PR

This, or even better, figure out why our existing tests didn't discover this. As mentioned, the only thing it takes for it to error out is to have a super simple Starlette app and request any endpoint, which we already have tests for, but for some reason, they didn't fail.
