chore: loosen ramda dependency range for openapi3-parser

[tklever]

Goal: Widen ramda dependency range to allow use of version ramda@0.27.2 in openapi3-parser.

Adding the carat in openapi3-parser's dependency configuration is consistent with the use of ramda in the api-elements package in this same monorepo:

api-elements.js/packages/api-elements/package.json

Line 25 in 0b3d062

"ramda": "^0.27.0"

Additionally, allowing downstream consumers to utilize ramda@0.27.2 allows them to use a version which includes this security fix ramda/ramda#3177

Bigger picture, as both of the libraries mentioned are included in the dependency tree of dredd (by way of dredd-transactions), unifying their use of this dependency will allow deduplication when using that project. The two independent versions of ramda can be seen here

└─┬ dredd@14.1.0
  ├─┬ dredd-transactions@10.1.0
  │ ├─┬ @apielements/core@0.2.1
  │ │ └─┬ api-elements@0.3.2
  │ │   └── ramda@0.27.2
  │ └─┬ @apielements/openapi3-parser@0.16.0
  │   └── ramda@0.27.0

Alternatives

This dependency could be updated to ^0.28.0, which is latest at time of writing, but this change seemed less invasive and aligned api-elements and openapi3-parser to be upgraded in tandem later
