chore(ci): fix missing SQLite3::SQLite3 target in cpp-static-test (#4276)

In e44eea5 I changed the SQLite3 target
for newer cmake but I also needed to update cpp-static-test to handle
it. The call to `find_depdencny_sqlite(SQLite3)` in
`AdbcDriverSQLiteConfig.cmake` creates the now-deprecated
SQLite::SQLite3 target so an alias is needed.
