Use package version of Roxygen

[AlexAxthelm]

The current docs-check action fails when RoxygenNote in DESCRIPTION is different than version released through CRAN/P3M.

Example of failing check:
https://github.com/RMI-PACTA/r2dii.plot/actions/runs/9752870368/job/26917168526

DESCRIPTION for same:
https://github.com/RMI-PACTA/r2dii.plot/blob/1103713b7cc6ec3b031e05d038a8d61793dc64fc/DESCRIPTION

Note RoxygenNote: 7.3.1, but released version is 7.3.2
