fix: JSON-LD context construction from a `dict` (#2306)

A variable was only being initialized for string-valued inputs, but if a `dict`
input was passed the variable would still be accessed, resulting in a
`UnboundLocalError`.

This change initializes the variable always, instead of only when string-valued
input is used to construct a JSON-LD context.

- Closes <https://github.com/RDFLib/rdflib/issues/2303>.
