Upgrade hermitised tools to the latest versions with:

	hermit upgrade

I manually check _all_ tools for major version updates, with

	hermit search --exact <TOOL>

None to be found.

Upgrade all go dependencies with

	go get -u ./...
	go mod tidy
	go get -C learn -u ./...
	go mod -C learn tidy

This is a relatively mechanical housekeeping commit.

Upgrade node tools such as stylelint and prettier with:

	npx --prefix .hermit/node -y npm-check-updates --packageFile .hermit/node/package.json -u
	npm --prefix .hermit/node install

Upgrade end-to-end testing tool playwright to the latest version 1.47.1.
It is installed locally with npm and used on CI via docker image:

Form npm upgrade run:

	npx --prefix e2e -y npm-check-updates --packageFile e2e/package.json -u
	npm --prefix e2e install
	npx --prefix e2e playwright install

For Makefile upgrade manually update OCI image line.
