Subject: Lua: split strings into words when treating them as Inline list
 (#7712)

Using a Lua string where a list of inlines is expected will cause the
string to be split into words, replacing spaces and tabs into
`pandoc.Space()` elements and newlines into `pandoc.SoftBreak()`.

The previous behavior was to treat the string `s` as `{pandoc.Str(s)}`.
The old behavior can be recovered by wrapping the string into a table
`{s}`.
