CLEANUP: Remove defunct values()

[HenrikBengtsson]

The values() function is defunct in favor of value(). To remove it from the package, the following packages need to be updated on CRAN first:

• [x] origami
  • Note: Request posted at https://github.com/tlverse/origami/issues/63 (2022-08-27)
  • Revdeps: cvCovEst, hal9001, haldensify, lmtp, scPCA, txshift
• [x] steps
  • Note: CRAN version imports values(), but GitHub version value(). See https://github.com/steps-dev/steps/issues/35 (2022-08-27, 2022-09-27, 2022-10-28)
