lang/fennel: update to fennel-1.3.1

1.3.1 / 2023-07-07

New Features

 * fennel.runtime-version will return version information as a
   table if given optional argument
 * Expose REPL's methods in the ___repl___ table, allowing method
   redefinition at runtime.
 * Allow following docstring with a metadata table syntax.
 * Return whole metadata table when metadata.get is called without
   a key.
 * Add :byte-escape option to fennel.view for overriding default
   char escapes
 * Generate man pages for fennel-api(3), fennel-reference(5), and
   fennel-tutorial(7) from their respective documentation.

Note for packagers: The man page fennel.1 has been moved to
man/man1/fennel.1 along with the new generated man pages. For build
scripts that copy files manually in lieu of make install, this may
require an update.
