Automatic Lua injection in lua commands and environments

[slideclimb]

Summary of additions and changes

• Make LatexParameter injectable.
• Add Lua commands to inline verbatim.
• Automatically inject Lua in Lua commands when a language with id Lua, lua, or LUA exists, i.e., when a Lua plugin is installed (tested with EmmyLua).

How to test this pull request

Check that language injection in environments still works, and that specifying the language with a magic comment takes precedence over Lua (for environments only, magic comments specifying the language are not supported for commands).

\documentclass{article}
\usepackage{listings}
\usepackage{luacode}

\begin{document}
    \directlua{tex.write()}
    \luaexec{tex.write()}

    \begin{luacode*}
        tex.write()
    \end{luacode*}

    
    %! language = Bibtex
    \begin{lstlisting}
        @article{identifier,
        author = {author},
        title = {title},
        journal = {journal},
        year = {year},
        }
    \end{lstlisting}
