Do not censor date breaks

[teunbrand]

This PR to the RC aims to fix a bug uncovered during reverse dependency checks.

Briefly, in #5569 we moved the censoring of breaks from the scales to the guides.
ScaleContinuousDate was overlooked, since it didn't do the usual scales::censor().
In turn, the scale could censor a break, which may result in mismatched labels/breaks.
In this PR, we remove the scale's censoring, because we handle that elsewhere now.

To reproduce issue with current RC:

library(ggplot2)

limits <- as.Date(c("2000-01-01", "2010-01-01"))

df <- data.frame(x = limits, y = 1:2)

ggplot(df, aes(x, y)) +
  geom_point() +
  scale_x_date(
    breaks = as.Date(c("2000-01-01", "2011-01-01")), #2nd breaks is oob
    labels = c("2000", "2011")
  )
#> Error in `scale_x_date()`:
#> ! `breaks` and `labels` have different lengths.

With this PR, the out-of-bounds break simply isn't rendered.

    breaks = as.Date(c("2000-01-01", "2011-01-01")),
    labels = c("2000", "2011")
  )
