[ERROR] metric_type should be metricType in Create Collection API docs

[ivhacks]

Where is the error
https://milvus.io/api-reference/restful/v2.4.x/v2/Collection%20(v2)/Create.md

How would you like to improve it
Change all instances of metric_type to metricType

I'm learning about Milvus and am trying to create a database to compare colors by Euclidean distance. When I run the following commands, as per the current docs, to create and describe a collection, its metric type shows as the default, COSINE (note the snake_case on metric_type):

curl -s --request POST "http://localhost:19530/v2/vectordb/collections/create" \
--data-raw '{
    "collectionName": "colors",
    "dimension": 3,
    "metric_type": "L2",
    "autoId": true
}'

curl -s --request POST "http://localhost:19530/v2/vectordb/collections/describe" --data-raw '{
    "collectionName": "colors"
}' | jq

However, when I change it to metricType, it properly comes back as using L2:

curl -s --request POST "http://localhost:19530/v2/vectordb/collections/create" \
--data-raw '{
    "collectionName": "colors",
    "dimension": 3,
    "metricType": "L2",
    "autoId": true
}'

curl -s --request POST "http://localhost:19530/v2/vectordb/collections/describe" --data-raw '{
    "collectionName": "colors"
}' | jq
