Use pyproject.toml's 'version' in build.sh #2895

Use pyproject.toml's (version = "5.0.14") via `poetry version` output:
e.g. "rockstor 5.0.14" to populate jslibs_version variable within build.sh.
Intended to ease project versioning/release strategies by having a single
point of reference for release versions. Typically rockstor-jslibs has a
GitHub released in parallel with rockstor-core.

Includes a minor build.sh logging fix re .env file source directory.
