The sentence:
"If you need to build an intermediate version of GCC in order to
bootstrap current GCC, consider GCC 9.5: it can build the current Ada
and D compilers, and was also the version that declared C++17 support
stable."
is possibly confusing because it globs Ada and D together, whereas Ada imposes
no further requirement over C++ (GCC 5.4+) unlike D (GCC 9.4+).
Tested with 'make doc', applied on the mainline.

* doc/install.texi (Prerequisites): Remove reference to Ada in
conjunction with GCC 9.5 and adjust its GCC version requirement.
