Update ts-invariant to avoid CSP-violating Function fallback. (#7414)

apollographql/invariant-packages#53

This update may also help with issues like #7406, where a patch
version update (from 0.5.0 to 0.5.1) is apparently not enough to force
a dependency like ts-invariant with multiple conflicting version
constraints (from @apollo/client and graphql-tools) to be updated,
since version 0.5.0 is still semantically compatible with the desired
minimum version 0.5.1, so ts-invariant remains outdated after updating
@apollo/client, despite the new version being clearly mandated in
@apollo/client/package.json.

After updating the minor version of ts-invariant in package.json (to
^0.6.0), there should be no risk of @apollo/client incorrectly resolving
the older ts-invariant@0.5.0 version, though there may end up being
multiple copies of ts-invariant in node_modules with different versions,
which is fine for this particular package.
