[SPARK-36177][R][TESTS][3.1] Disable CRAN in branches lower than the latest version uploaded

[HyukjinKwon]

What changes were proposed in this pull request?

This PR proposes to skip the CRAN check in old branches (than the latest version uploaded to CRAN)

Why are the changes needed?

Same as #33390. Spark 3.2.0 will very likely come first before Spark 3.1.x.

Does this PR introduce any user-facing change?

No, dev-only.

How was this patch tested?

It will be tested in the CI at this PR.

cc @gengliangwang and @dongjoon-hyun WDYT? The CRAN check is not being failed in branch-3.1 yet but it will be failed once Spark 3.2 is released.

I would just like to fix it now together with #33390 for simplicity since 3.2 will come first before 3.1.x very likely.

If you guys have some concerns, I am also fine with waiting and/or dropping this in branch-3.1.

Thanks for taking care of this.
