Using old guzzlehttp/psr7

[leeyuentuen]

Hi,
I need to use the old guzzlehttp/psr7 package (1.8.3) guzzle/psr7#489 (comment)
but after the latest update of security advisories it required 1.8.4

which gives me now the error:

#11 36.60 - Root composer.json requires guzzlehttp/psr7 1.8.3 -> satisfiable by guzzlehttp/psr7[1.8.3].
#11 36.60 - roave/security-advisories dev-master conflicts with roave/security-advisories dev-master.
#11 36.60 - Root composer.json requires roave/security-advisories dev-master -> satisfiable by roave/security-advisories[dev-master].

@leeyuentuen this package is explicitly designed to deny usage of insecure versions of a library: that's its core feature.

indeed, I saw it, we will make the change at our side
