[Feature Request]: remove `{tidyselect}` from `{teal.transform}`

Consider if we can substitute `{tidyselect}` package usage with a function from `base`.
`{tidyselect}` is only used once `get_reshape_call()` in `R/get_dplyr_call.R`.

I don't think this function is even used in `teal.transform` or outside of `teal.transform`

Part of https://github.com/insightsengineering/teal.transform/issues/194

Start in R/get_dplyr_call.R, inspect get_reshape_call(), and search the package for references to that function and {tidyselect}. Check the package dependency declarations and existing checks. Done means {tidyselect} is no longer needed without breaking the package or its transformation behavior.
