[R-pkg-team] Bug#1102590: r-cran-fansi fails to migrate to testing

[Rebecca N. Palmer]

This passes its tests in unstable but still fails them in testing.  I 
don't know whether this is caused by R 4.5.0 vs 4.4.3 or by some other 
package.

As far as I know, nothing is actually wrong with the old (testing) 
version other than that it's old, so just accepting that the new version 
won't migrate (and doing a +really revert if any unrelated bug fixes are 
needed during the freeze, which is unlikely) is an option.
