move dot-prop to > 5.1.0

[iamcdonald]

This is used across a few other packages and currently relies on a dot-prop version that has the following security vulnerability https://nvd.nist.gov/vuln/detail/CVE-2020-8116

This just ups the dot-prop version to >5.1.0.

I've ran the tests and everything looks fine.

This is dependent on being rebased after #4 has been merged.

@stevemao - could you please approve this pull request... This is really important as it resolves a security vulnerability..
Let me know if I can help in any way

Sorry just saw this. CI failed. Looks like this is still on an old version of node. Could you bump the version of node too? Thanks

[iamcdonald]

Hi folks,

I’ve raised another PR to fix the tests (it’s an outstanding issue rather than something caused by this version bump).

#4

@stevemao If we could merge that first I’ll rebase this PR and then there’ll be no test failures.

[stevemao]

Should this be a major bump or minor?

[iamcdonald]

I would say minor or bugfix Given that it’s not actually changing the api.

@iamcdonald I had to update nodejs versions to make it work. So I published as major release.
