pkgdown: wrong documentation for methods CreateRunOptions and CreateCalibOptions

Got these warnings in pkgdown:

Warning: Failed to parse usage:
S3method(`CreateCalibOptions`, `GRiwrmInputsModel`)(x, ...)
CreateCalibOptions(x, ...)
S3method(`CreateCalibOptions`, `InputsModel`)(x, ...)
S3method(`CreateCalibOptions`, `character`)(x, ...)
S3method(`CreateCalibOptions`, ``function``)(x, ...)
Warning: Failed to parse usage:
S3method(`CreateRunOptions`, `GRiwrmInputsModel`)(x, IniStates = NULL, ...)
CreateRunOptions(x, ...)
S3method(`CreateRunOptions`, `InputsModel`)(x, ...)
S3method(`CreateRunOptions`, `character`)(x, ...)
S3method(`CreateRunOptions`, ``function``)(x, ...)

The issue comes from the double back-ticks on methods for function objects.

This is related to a bug in roxygen2 https://github.com/r-lib/roxygen2/issues/906 but it seems to have been already fixed...
