Upgrade vesion of fastapi to 0.103.1

[cquike]

Description

Hi, this PR tries to solve the issue that the fastapi python package is currently broken (https://trac.macports.org/ticket/54100). I created myself that ticket and I have now decided to see how it can be fixed.

The solution is to bump the version of fastapi to 0.103.1. It seems that fastapi is still not compatible with starlette 0.31.1 (tiangolo/fastapi#9939) although it seems that some compatibility is already done (tiangolo/fastapi#10194). This is not ideal, since it might be that some functionality of fastapi does not work properly, but at least it is better that the current situation in which it does not work at all.

This PR also changes the build system from flit to hatchling, that has happened in the meantime (tiangolo/fastapi#5240).

Additionally, it removed python37 support, since the starlette portfile does not support it anymore (https://github.com/macports/macports-ports/blob/master/python/py-starlette/Portfile)

The Portfile contain not tests, so I could not verify that, but I have tested it with an application that uses fastapi and things seems to be working fine, although admittedly such application does not exercise the full API of fastapi, of course.

Note that there is already a PR addressing something similar to this (#19950). However, in this PR I don't try to support python 3.11 for the time being, since that gives an error with pydantic. It also needs to patch pyproject.toml, to ensure that the version of starlette in the metadata is consistent with the version in macports. Also, it changes the build system dependency as mentioned to hatchling. Also the typing-extensions dependency was missing.

All in all, this PR tries to solve the immediate problem of the broken fastapi currently shipped, even if there are potentially some fixes to be done in the future (full support for starlette 0.31.1 and fix the errors in python 3.11).

Thank you for this submission, @cquike. Two things:

1. The commit message should be of the format, <port name>: <description>. So instead of Upgrade vesion of fastapi to 0.103.1, it should be py-fastapi: update to 0.103.1.
2. You can reference the Trac issue in the commit message. You can add Closes: https://trac.macports.org/ticket/54100 as a second line to the commit message, after making the change above, and the Trac issue will be closed when this is merged.

Please amend and force push this branch to replace the commit with your new one incorporating the above changes.

I edited the original request to fix [X ] and [ X] into [X] so the system would register them correctly.

The Trac issue did get closed on merge, but @cquike, I think you linked to the wrong issue. Trac issue 54100 is referencing get_iplayer, and not py-fastapi.
