Restrict SQLite to 1.x

[mamhoff]

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

It looks like this PR is missing a label to determine the type of change it introduces. The maintainer should add one of the following labels:

• bug for bugfixes.
• enhancement for new features and improvements.
• documentation for documentation changes.
• security for security patches.
• removed for feature removals.
• infrastructure for internal changes that should not go in the changelog.

Additionally, the maintainer may also want to add one of the following:

• breaking for breaking changes.
• deprecated for feature deprecations.

Once the correct labels have been set, simply remove the needs changelog label label from this PR so I can merge it.
