Release a new gem version

[isaacbowen]

5.4.0 was the last version cut, and that was back in July of 2022.

My specific motivation in filing this is that {%- endraw -%} didn't start working until https://github.com/Shopify/liquid/commit/74e505f, in February, and I'd like to be able to use that with an official stable release. :D

Now that it's nearing the end of September 2023 perhaps a new v5.5 release? Thanks in advance
