Allow entities to be symbols in "clojure -T" commands

[tengstrand]

Is your feature request related to a problem? Please describe.
Today we have to give entity values as strings, e.g.:
clojure -Tpoly create entity '"workspace"' name next-gen top-ns com.my-company

Describe the solution you'd like
It would be good if the tool allowed us to pass them in as symbols:
clojure -Tpoly create entity workspace name next-gen top-ns com.my-company

See thread in Slack.

When this is released, make sure to update the Clojure CLI Tool section in the documentation.

This functionality can be tested now with e.g. these statements (the SHA points to the last commit in the issue-154 branch):

clojure -Ttools install io.github.polyfy/polylith '{:git/sha "d38c1ad938cc73298b592beb64157d9c80048424" :deps/root "projects/poly"}' :as poly
clojure -Tpoly create entity workspace name myworkspace top-ns com.my-company
