bind_rows() only flattens S3 lists that inherit from list (#3924)

Code
  bind_rows(lst1)
Condition
  Error in `bind_rows()`:
  ! Argument 1 must be a data frame or a named atomic vector.

bind_rows() validates lists (#5417)

Code
  bind_rows(list(x = 1), list(x = 1:3, y = 1:2))
Condition
  Error in `vctrs::data_frame()`:
  ! Can't recycle `x` (size 3) to match `y` (size 2).

bind_rows() give informative errors

Code
  # invalid .id
  df1 <- tibble(x = 1:3)
  df2 <- tibble(x = 4:6)
  (expect_error(bind_rows(df1, df2, .id = 5)))
Output
  <error/rlang_error>
  Error in `bind_rows()`:
  ! `.id` must be a single string, not the number 5.
Code
  # invalid type
  ll <- list(tibble(a = 1:5), env(a = 1))
  (expect_error(bind_rows(ll)))
Output
  <error/rlang_error>
  Error in `bind_rows()`:
  ! Argument 2 must be a data frame or a named atomic vector.
Code
  df1 <- tibble(a = factor("a"))
  df2 <- tibble(a = 1L)
  (expect_error(bind_rows(df1, df2)))
Output
  <error/vctrs_error_ptype2>
  Error in `bind_rows()`:
  ! Can't combine `..1$a` <factor<4d52a>> and `..2$a` <integer>.
Code
  # unnamed vectors
  (expect_error(bind_rows(1:2)))
Output
  <error/rlang_error>
  Error in `bind_rows()`:
  ! Argument 1 must be a data frame or a named atomic vector.
