Additional `cs:info` properties throw warning on PHP 8.2

[adam-vessey]

Please follow the general troubleshooting steps first:

• [ ] I read the README and followed the instructions.
• [ ] I am sure that the used CSL metadata follows the CSL schema.
• [ ] I use a valid CSL stylesheet

Bug reports:

Warnings emitted under PHP 8.2 due to other CSL 1.0.1 properties.

Used CSL stylesheet:

http://www.zotero.org/styles/chicago-fullnote-bibliography

chicago-fullnote-bibliography.csl

Used CSL metadata

Please replace these lines with your used metadata, for instance:

Not relevant for the issue, any will do.

The warnings in particular:

Deprecated function: Creation of dynamic property Seboettg\CiteProc\Root\Info::$category is deprecated in Seboettg\CiteProc\Root\Info->__construct() (line 62 of /var/www/html/vendor/seboettg/citeproc-php/src/Root/Info.php).

Deprecated function: Creation of dynamic property Seboettg\CiteProc\Root\Info::$updated is deprecated in Seboettg\CiteProc\Root\Info->__construct() (line 62 of /var/www/html/vendor/seboettg/citeproc-php/src/Root/Info.php).

It appears that chicago-fullnote-bibliography defines cs:info/cs:category elements as per the 1.0.1 spec, which throws this warning.

In the warnings, it's flagging:

• category
• summary
• updated and
• rights

However, it appears that this could pop for other allowed properties, such as:

• title-short
• issn/eissn/issnl
• published

Naively, these could probably be stashed in something like:
