shiboken: update formula to use py311

[ipatch]

• Have you ensured that your commits follow the commit style guide?

brew style freecad/freecad/[NAME_OF_FORMULA_FILE] 

output from running above command should output something similiar to the below

1 file inspected, no offenses detected

• Have you ensured your commit passed audit checks, ie.

brew audit freecad/freecad/[NAME_OF_FORMULA_FILE] --online --new-formula

---

Not all PRs require passing these checks ie. adding [no ci] in the commit message will prevent the CI from running but PRs that change formula files generally should run through the CI checks that way new bottles are built and uploaded to the repository thus not having to build all formula from source but rather installing from a bottle (significantly faster 🐰 ... 🐢)

need to resolve the below issue,

the below error message is possibly a false positive due to the way homebrew test-bot is setup,

==> brew bottle --merge --write --no-commit --no-all-checks ./shiboken2@5.15.11--5.15.11_2.ventura.bottle.json --keep-old

it seems pr-pull may not be able to overwrite existing packages? 😕

Error: Failure while executing; `/usr/local/bin/brew pr-upload --debug` exited with 1.

/usr/bin/env /usr/local/opt/skopeo/bin/skopeo inspect --raw docker://ghcr.io/freecad/freecad/shiboken2/5.15.11:5.15.11_2 --creds=ipatch:******

Rerun with --verbose to see the original backtrace

need to look and see if there is a flag for pr-pull that can/will overwrite an existing package if it exists, or i need to possibly bump the revision. 🤔

also,

Warning: Calling `brew pr-pull --no-autosquash` is deprecated! There is no replacement.

did not see a flag listed for the pr-pull command that could overwrite the existing package / update the existing package. 🤦‍♂️
