chore: update version for fastapi, starlette and uvicorn

[jiahao1553]

Update versions for fastapi, starlette and uvicorn so that integration with r2r package can be done. Currently, there are dependency conflicts:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
chainlit 1.1.306 requires fastapi<0.111.0,>=0.110.1, but you have fastapi 0.109.2 which is incompatible.
chainlit 1.1.306 requires starlette<0.38.0,>=0.37.2, but you have starlette 0.36.3 which is incompatible.
chainlit 1.1.306 requires uvicorn<0.26.0,>=0.25.0, but you have uvicorn 0.27.1 which is incompatible.
