minor: update babel deps in lockfile

Without this, received error `No "exports" main resolved in ...`

According to [this issue](babel/babel#11216 (comment)),
it is just the result of an incompatibility between a node version and a
babel version which can be worked around either by upgrading node or by
grabbing more recent versions of babel dependencies.

It may be perfectly sensible not to accept this PR as it relates to a
potentially outdated nodejs version.
