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.
