Restrict SQLite to 1.x

They just released sqlite3 2.0.0, but ActiveRecord's sqlite3 adapter doesn't know about this yet, leading to conflicting sqlite3 gems in specs.

This is probably a temporary fix until ActiveRecord learns the news.

See https://github.com/rails/rails/blob/main/activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb#L14
and https://github.com/sparklemotion/sqlite3-ruby/blob/main/CHANGELOG.md
