Update key and index for a tsibble

update_tsibble(x, key = NULL, index = NULL, regular = NULL,
  validate = TRUE)

`x`	A tsibble.
`key`	Variable(s) that define unique time indices, used in conjunction with the helper `id()`. If a univariate time series (without an explicit key), simply call `id()`.
`index`	A bare (or unquoted) variable to specify the time index variable.
`regular`	Regular time interval (`TRUE`) or irregular (`FALSE`). The interval is determined by the greatest common divisor of index column, if `TRUE`.
`validate`	`TRUE` suggests to verify that each key or each combination of key variables leads to unique time indices (i.e. a valid tsibble). If you are sure that it's a valid input, specify `FALSE` to skip the checks.

Default NULL inherits attributes from x.
