TraceState does not check illegal inputs

[tohidemyname]

Describe your environment

OS: Windows
Python version: Python 3.13
SDK version: the latest
API version: the latest

TraceState.add() does not fully check whether the inputs are correct.

What happened?

TraceState.add() should reject the illegal inputs.

Steps to Reproduce

Here is my test case:

`from opentelemetry.trace import TraceState

Java constants mapped to Python

EMPTY = TraceState()
FIRST_VALUE = "first_value" # Adjust to match your test's actual constant
class MyTestCase(unittest.TestCase):

def test_valid_long_tenant_id(self):
    result = EMPTY.add("12345678901234567890@nr", FIRST_VALUE)
    assert result.get("12345678901234567890@nr") == FIRST_VALUE


def test_vendor_id_longer_than_13_characters(self):
    with self.assertRaises(Exception) as context:
        EMPTY.add("1@nrabcdefghijkl", FIRST_VALUE)
    self.assertTrue('This is broken' in context.exception)

def test_vendor_id_longer_than_13_characters_long_tenant_id(self):
    with self.assertRaises(Exception) as context:
        EMPTY.add("12345678901234567890@nrabcdefghijkl", FIRST_VALUE)
    self.assertTrue('This is broken' in context.exception)

def test_tenant_id_longer_than_240_characters(self):
    tenant_id = "a" * 241
    with self.assertRaises(Exception) as context:
        EMPTY.add(f"{tenant_id}@nr", FIRST_VALUE)
    self.assertTrue('This is broken' in context.exception)

def test_non_vendor_format_first_key_character(self):
    with self.assertRaises(Exception) as context:
        EMPTY.add("1acdfrgs", FIRST_VALUE)
    self.assertTrue('This is broken' in context.exception)`

Shall reject.
