SCRAPEGRAPHAI_TELEMETRY_ENABLED=false does not disable telemetry

[hakoke]

The README (Telemetry section) says usage collection can be disabled by setting SCRAPEGRAPHAI_TELEMETRY_ENABLED=false. Setting it has no effect, with any value.

The check in scrapegraphai/telemetry/telemetry.py (lines 47-53 on current main) only tests whether the variable exists, then reads the telemetry_enabled key from ~/.scrapegraphai.conf instead of the variable's value:

if os.environ.get("SCRAPEGRAPHAI_TELEMETRY_ENABLED") is not None:
    try:
        telemetry_enabled = config_obj.getboolean(
            "DEFAULT", "telemetry_enabled"
        )
    except Exception:
        pass

On a default install that key does not exist, so getboolean raises NoOptionError, the bare except swallows it, and the flag stays at its default of enabled. Repro:

import os, subprocess, sys

for val in ("false", "False", "FALSE", "0", "no", "off", "true"):
    out = subprocess.run(
        [sys.executable, "-c",
         "from scrapegraphai.telemetry import telemetry;"
         "print(telemetry.g_telemetry_enabled)"],
        env={**os.environ, "SCRAPEGRAPHAI_TELEMETRY_ENABLED": val},
        capture_output=True, text=True,
    )
    print(val, "->", out.stdout.strip())

prints True for every value on 2.1.6. Since log_graph_execution sends user_prompt, website_content and llm_response when those fields are all present, the documented opt-out matters. disable_telemetry() does work, but only for people who found it in the source.

Tested on 2.1.6 (current main), Python 3.12, Windows 11. I have a small fix ready and will open a PR in a few minutes.
