Installation: needs overview of installation methods

[daipom]

Describe the bug

https://docs.fluentd.org/installation

There are multiple installation methods.
However, there is no overview of it.
So, it is difficult to know which installation method to choose.

Link to the problematic documentation

Expected explanation

Seems like a good idea to have the same overview as the next one.
