Run regressions tests on both Postgres 14 and 15 (#4192)

This PR adds tests runs on Postgres 15 and created unified Allure report
with results for all tests.

- Split `.github/actions/allure-report` into
`.github/actions/allure-report-store` and
`.github/actions/allure-report-generate`
- Add debug or release pytest parameter for all tests (depending on
`BUILD_TYPE` env variable)
- Add Postgres version as a pytest parameter for all tests (depending on
`DEFAULT_PG_VERSION` env variable)
- Fix `test_wal_restore` and `restore_from_wal.sh` to support path with
`[`/`]` in it (fixed by applying spellcheck to the script and fixing all
warnings), `restore_from_wal_archive.sh` is deleted as unused.
- All known failures on Postgres 15 marked with xfail
