electrum 4.5.8 won't start with libsecp256k1 0.6.0

Basically all I've got is in the title.

ImportError: Failed to load libsecp256k1
  0.21 | E | ecc_fast | libsecp256k1 library failed to load. exceptions: [OSError('/usr/lib/python3.12/site-packages/electrum/libsecp256k1.so.2: cannot open shared object file: No such file or directory'), OSError('/usr/lib/python3.12/site-packages/electrum/libsecp256k1.so.1: cannot open shared object file: No such file or directory'), OSError('/usr/lib/python3.12/site-packages/electrum/libsecp256k1.so.0: cannot open shared object file: No such file or directory'), OSError('libsecp256k1.so.2: cannot open shared object file: No such file or directory'), OSError('libsecp256k1.so.1: cannot open shared object file: No such file or directory'), OSError('libsecp256k1.so.0: cannot open shared object file: No such file or directory')]

Maybe it's just me, maybe it's a downstream Gentoo bug. Idk, Idc. If you cannot reproduce this or confirm otherwise, just close the ticket.

I downgraded back to 0.5.1 and it runs fine, but I suspect this is related to #9239

related to spesmilo/electrum-ecc#4, though the 4.5 branch does not use the electrum-ecc library, only master does

load_library() in ecc_fast.py tries to load libsecp256k1.so.2, libsecp256k1.so.1, libsecp256k1.so.0, but libsecp256k1 0.6.0 provides libsecp256k1.so.5!

The 0.5.1 package I have installed on my Gentoo provides symlinks and a file:

/usr/lib64/libsecp256k1.so -> libsecp256k1.so.2.2.1
/usr/lib64/libsecp256k1.so.2 -> libsecp256k1.so.2.2.1
/usr/lib64/libsecp256k1.so.2.2.1

The first one seems like the best fit. If you worry about lib API functionality, you wouln't hardcode the "valid" version numbers, instead run some library functions test (there might be some libs or tools for that).
