Text with camel case breaks syntax

[dzwarg]

Hello,

First of all, thank you for writing this plugin for vscode, it's been really helpful and a big improvement in productivity since our team switched to using Hurl.

Now the issue: it seems the syntax highlighting seems to get confused when it encounters a camel case ("camelCase") term, such as:

# Example 1:
#
head_ref_oid: jsonpath "$.data.repository.developPRs.nodes[0].headRefOid"
                                                 ^-- here

Screenshot for Example 1:

# Example 2:
#
POST https://automation.atlassian.com/pro/hooks/deadbeef
[Options]
skip: false
variable: name="JIRA Automation"
```json
{
  "issues": ["{{issue_id}}"],
  "data": {
    "releaseVersion": "{{version}}",
            ^-- here
    "suffix": "CSS",
    "product": ""
  }
}
```
HTTP 200

# Example 3:
#
PATCH https://my.json.api
Authorization: Bearer {{access_token}}
[Options]
skip: false
variable: name="Authorize Deployment"
```json
{
  "numberFormat": [
         ^-- here
    [
      "General",
      "General",
      "General",
      "General",
      "General",
      "General",
      "General"
    ]
  ]
}
```
HTTP 200
