Update secrets-client-component.md

[batsauto]

There might be a possible typo in the section about downloading the secrets cli

export PATH=~/bini:$PATH

didn't work on my machine.

export PATH=~/bin:$PATH

Did work.

Before:

mkdir ~/bin
cd ~/bin
curl -o secrets http://repo1.maven.org/maven2/com/oneops/secrets-cli/1.0.3/secrets-cli-1.0.3-executable.jar
chmod a+x secrets
export PATH=~/bini:$PATH

After:

mkdir ~/bin
cd ~/bin
curl -o secrets http://repo1.maven.org/maven2/com/oneops/secrets-cli/1.0.3/secrets-cli-1.0.3-executable.jar
chmod a+x secrets
export PATH=~/bin:$PATH
