glDebugMessageInsert() GL_INVALID_VALUE claim does not match specification

https://registry.khronos.org/OpenGL-Refpages/gl4/html/glDebugMessageInsert.xhtml says:

> GL_INVALID_VALUE is generated if the length of the message is greater than the value of GL_MAX_DEBUG_MESSAGE_LENGTH

Specification says:

> An INVALID_VALUE error is generated if the number of characters in buf, excluding the null terminator when length is negative, is not less than the value of MAX_DEBUG_MESSAGE_LENGTH.

My interpretation of specification is that when length is not negative, INVALID_VALUE should not happen.

For reference, https://registry.khronos.org/OpenGL-Refpages/gl4/html/glPushDebugGroup.xhtml says:

> GL_INVALID_VALUE is generated if length is negative and the number of characters in message, excluding the null-terminator, is not less than the value of GL_MAX_DEBUG_MESSAGE_LENGTH.

Start with the glDebugMessageInsert() reference page linked in the issue and compare its GL_INVALID_VALUE wording with the OpenGL specification and the glPushDebugGroup() reference page. Locate the source for the affected reference text, update the condition to match the specification, and regenerate or verify the HTML so the published wording is consistent.
