Debians lintian nagging about build-backend.

[kathenas]

Version: rednotebook git master.

Under Debian, lintian will nag about the below.

I: rednotebook source: missing-prerequisite-for-pyproject-backend setuptools.build_meta (does not satisfy python3-setuptools:any, pybuild-plugin-pyproject:any) [pyproject.toml:3]

Changing:

build-backend = "setuptools.build_meta"

to

build-backend = "setuptools.build_meta:__legacy__"

seems to correct the issue. Not being big on python builds, this report is more speculative.

Thanks for the report! The solution looks reasonable to me. I'm AFK so can't change this now. But happy to accept a PR:)
