Http input plugin "Content-Type: application/json; charset=utf-8" not working

[jamesstojan1]

Describe the bug
The Http input plugin rejects json when the content type when a charset is included. Given that the parser is expecting utf8 json it isn't unreasonable to allow it as the character set.

To Reproduce
Config
[INPUT] name http host 0.0.0.0 port 5170

Post message
curl --location --request POST 'http://localhost:5170' \ --header 'Content-Type: application/json; charset=utf-8' \ --data-raw '{ "log": "some log entry" } '

Get error message "error: invalid 'Content-Type'"

Expected behavior
That the http request would be accepted and processed

Additional context
Allowing charset=utf-8 would make the http input plugin more flexible especially when working with applications that automatically set the character set.

You can work around this of course by removing the charset from the header.
