Update logfmt.md with improved python package

The kr/logfmt package is no longer maintained or functional. The package has since passed to a new maintainer, but the package is still unmaintained or functional. The new maintainer now recommends jteppinette/python-logfmter (https://github.com/wlonk/logfmt-python/commit/1ee07cafc315d71fd6b1150bbaeee2de6e732671).
