Update eslint dependencies

Resolves #4.

I made a separate commit for the naming-convention rule since that one can still cause some discussion. This was the original rule in the config we're using.

Using the original rule as it was written required us to have all our boolean parameters/variables start with has/is/etc. This caused issues with many external calls such as enabling quad mode for SparqlAlgebra.js, setting objectMode for Node streams, etc. There were several files where I needed to disable the rule for multiple lines (and there were still 150 errors remaining when I gave up). It also would require us to change our permissions object from read/write/append to canRead/canWrite/canAppend which is less clean imo.

I then tried using a combination of the default settings and the config by still using strictCamelCase and StrictPascalCase, but that has as disadvantage that we for example can never use URI as part of a variable. E.g, can't have a variable called childURIs, would have to be childUris. Same for baseIRI, etc.

So I just used normal camel case/Pascal case rules since URIs/IRIs are sort of important for Solid. But this one is a separate commit so it can still easily be changed.

Still have to disable the rule in the URI constants file but that was to be expected.

I would actually be fine with that though :-)
But no strong opinion.

I have no strong opinion about it either so I just picked the one where I didn't have to rename a bunch of functions and variables 😄
