GH-48010: [C++] Update bundled RE2 from 2022-06-01 to 2023-03-01 (#48011)
### Rationale for this change
Arrow currently bundles RE2 version 2022-06-01, which fails to build on
musl libc systems (Alpine Linux) due to missing `#include <cstdint>` in RE2's
`util/pcre.h`. This affects R package installations from source on Alpine
(#46769), C++ builds on Alpine (#43350, #41619), and causes CRAN extended musl
checks to fail.
### What changes are included in this PR?
Updated `cpp/thirdparty/versions.txt`
### Are these changes tested?
Yep - CI checks
### Are there any user-facing changes?
No.

2023-06-01
