[BUG] Breaking Change: Boolean true Converted to 1, Causing Illegal Argument Exception

[dmnlk]

What is the bug?

I have been testing and validating the implementation of the following PR in my project.
I am using GuzzleHttp as the client, but I noticed one breaking change.

When passing true as a request parameter (e.g., for the refresh option in an index operation), it gets converted into 1 during the request, which results in an illegal_argument_exception.
The detailed error message is:
Failed to parse value [1] as only [true] or [false] are allowed.

While options like refresh can be passed as strings (since they seem to be enums), options like require_alias are booleans, which makes this change problematic.

I believe this behavior should be corrected.

How can one reproduce the bug?

specify require_alias is true

What is the expected behavior?

collectry passing true

What is your host/environment?

Do you have any screenshots?

@dmnlk can you provide the version of opensearch-php you are using, and whether you are using the ClientBuilder to create the client?
