[RISCV] Bump Pointer Masking extension version (llvm#96715)

These extensions had their version number bumped and still experimental
(under public review). I didn't see anything in the [commit
history](https://github.com/riscv/riscv-j-extension/commits/master/)
since llvm#79929 that would warrant a change to the implementation of
pointer masking in the compiler.

 The primary goal of experimental support is to assist in the process of ratification by providing an existence proof of an implementation, and simplifying efforts to validate the value of a proposed extension against large code bases.  Experimental extensions are expected to either transition to ratified status, or be eventually removed.  The decision on whether to accept an experimental extension is currently done on an entirely case by case basis; if you want to propose one, attending the bi-weekly RISC-V sync-up call is strongly advised.
