using image_regression on bytesIO output raise an SSL socket error

[12rambau]

I'm using the following code in my tests and I receive a weird error after completion:

    def test_plot_by_features(self, gaul, image_regression):
        fc = gaul.limit(10).select(["ADM0_CODE", "ADM1_CODE", "ADM2_CODE"])
        fig, ax = fc.geetools.plot_by_features()
        fig.savefig(buf := io.BytesIO())
        image_regression.check(buf.getvalue())

sys:1: ResourceWarning: unclosed <ssl.SSLSocket fd=10, family=2, type=1, proto=6, laddr=('172.16.5.4', 40806), raddr=('142.250.180.10', 443)>

My guess is taht there are a missing context managers either on your side or mine. I'll continue to investigate but I wanted to record it before I forgot.
