Regexes are not supported in EDN, and therefore not supported when Codox is used from tools.deps

[pmonks]

EDN does not support regular expression literals (#"<regex-content>"), and because tools.deps uses EDN for defining and configuring build tasks (such as Codox), the use of regular expressions in Codox's configuration (e.g. in the :namespaces option) limits what tools.deps users can do with Codox.

Not sure what a good solution might look like, until/unless EDN supports regular expressions (which doesn't seem likely), but thought I'd raise this anyway in case it bites anyone else.
