build(deps): pin firebase-js-sdk to exact version not semver

this is important because lockfile recreation may allow this to slip,
at which point `yarn compare:types` starts to fail

we rely on exact versions in practice as we make changes to adopt new
versions and may even rely on bug-compatibility internally until a
new version is qualified / formally adopted
