Add CPython 3.12.0

It seems that pyenv cannot install 2.7.18 on Mac M1 (Apple ARM).

openssl 1.0.2 does not have ARM support. M1 support was added in 1.1.1i according to
https://www.openssl.org/news/cl111.txt

All include directories should go into CPPFLAGS.
XCode SDK was being added to CFLAGS instead
which caused old Tcl/Tk in the SDK to override a newer one in Homebrew.

Update openssl url for 3.12.0rc2

The old 3.1.1s URL returns a 404

3.7 is EOL since 2023-06-27

use -I with ensurepip

fix a typo in README.md

According to the POSIX spec, an unescaped backslash not followed by
an escapable character is undefined behavior,
and it has become an error in GNU grep 3.8 (2022-09-02).

The -s flag assures that nothing can be installed to user site-packages
but doesn't keep ensurepip from looking there for Pip.
If Pip is installed in the user site-packages directory, pip won't be installed
for the newly built python -- and its shim won't be created.
-I makes the build install Pip in any case.
The user site-packages installation will override it --
but we'll have the shim at least.

Add CPython 3.8.18, 3.9.18, 3.10.13, 3.11.5

Add CPython 3.12.0rc1

Guthub have recently preinstalled x64 Homebrew OpenSSL to stock MacOS runners. This has caused FreeBSD OpenSSL detection logic to erroneously trigger when running FreeBSD tests in MacOS because their paths happened to coincide.

Replaced checking a specific path with checking with pkg.

Add new anaconda and miniconda definitions

This adds anaconda 2023.03, anaconda 2023.07, miniconda 23.3.1, and
miniconda 23.5.0.

Anaconda and miniconda have changed their version string format again,
so the parsing needs to be done differently. `add_miniconda.py` can now
parse all existing definition files properly.

This makes it easier to fix file names that cannot be parsed using the
current logic.
