Links still to deployer.phar instead of dep

[alexgit2k]

The changelog of https://github.com/deployphp/deployer/releases/tag/v7.0.0-rc.9 says:

Phar renamed back to dep from deployer.phar + source code also available now.

However, assets since rc.9 and download-page still link use deployer.phar:

• https://github.com/deployphp/deployer/releases/tag/v7.0.0
• https://github.com/deployphp/deployer/releases/tag/v7.0.0-rc.9
• https://deployer.org/download

Dep only in composer package.
