[UX] Quote individual dependencies in the list logged to console

[webknjaz]

See

* Installing packages in isolated environment... (Cython, expandvars, setuptools-scm-git-archive >= 1.1; python_version < '3.7', setuptools-scm[toml] >= 3.5, < 7.0; python_version < '3.7', setuptools-scm[toml] >= 7.0; python_version >= '3.7', setuptools>=45, toml)

There's a few dependencies that are conditional on environment and/or have complex version specifiers. In it, a comma is use in two contexts — as a package request separator and as a separator of parts of a version specifier. This is something an inexperienced individual could easily get confused about when reading the logs.

I think that these deps should be repr()ed or smth similar for clarity.

PR improving the CLI output welcome :)

It seems like here's a PR now: #711. UPD: that PR got stalled and subsequently closed. There was a suggestion to go for a multi-line list instead of quoting the entries that a new PR author should implement — #711 (comment).

Addressed in #749.
