Formatter doesn't retrieve value correctly if value name in schema has capital letters

[bk201-]

In the schema, there is a header value with capital letters

"parameters": [
          {
            "name": "X-Customer-Code",
            "in": "header",
            "description": "Company Profile ID, it can be found on JetBrains Account portal near the company name",
            "schema": {
              "type": "string"
            }
          }
        ]

However, api/core transforms all headers to lowercase: https://github.com/readmeio/api/blob/cc5ee91b1d4d550c0c014875c74c5403762e42c8/packages/core/src/lib/prepareParams.ts#L367

Therefore formatted can't retrieve this field from data here:

oas/packages/oas-to-har/src/index.ts

Line 46 in 77ba97d

if (typeof values[type][param.name] !== 'undefined') {

This issue also exist in api@6.1.1 package
