Version 1.3.1 stipulates unworkable "supported engine"

[robross0606]

The latest 1.3.1 version of pdf2json shows this when I update:

npm WARN notsup Unsupported engine for [email protected]: wanted: {"node":">=14.18.0","npm":">=6.14.15"} (current: {"node":"14.18.1","npm":"6.14.12"}) 
npm WARN notsup Not compatible with your version of node/npm: [email protected]

My version of node is supported, but the version of npm requires something newer than that version of node installs. That would mean, in order to use this library in a build process (like a Jenkins pipeline or container), I would need to install not only a specific image including node 14 (14.18.1 is newest available release) but also update npm separately to a newer version than what is supplied by that binary (6.14.12).
