Method parameter decorators cause typescript build to fail.

[IhsanMujdeci]

Describe the bug
Not sure if this is a bug or intended.
The body function and other parameter functions aren't actually functions that typescript can build.
Other decorators seem to be fine and actually build and resolve to a value e.g. class decorators and method decorators.

To Reproduce
Steps to reproduce the behavior:

1. npx @airtasker/spot init
2. npx tsx ./api.ts
3. Console error TypeError: decorator is not a function (it seems to error on the first instance of use of the @body decorator).

This error also appears while using SWC, I haven't tired TSC.

Expected behavior
I would expect that typescript would be able to build the solution but it seems it cant.
The @body and other method parameter decorators don't resolve to a real value, they are "undefined"
Actual building of API docs works fine via npx @airtasker/spot generate --contract api.ts
