Replace hyphen as dash with "Em Dash" unicode character (U+2014)

This commit replaces hyphen characters used as dash with the actual unicode character for dash. It avoids using HTML character entity reference (—), because IMHO it would make it a bit harder to read documents as plain markdown files on your local text editor.

 ### How do I get started with Matrix?
 
-One of [Matrix](https://matrix.org/)'s distinguishing strengths (compared to other chat networks) is its decentralized nature. There's not just one entity (company, organization) controlling the servers. Rather there's thousands of servers operated by different people - one server being insecure, slow or disrespective toward its users does not affect the rest of the network. To participate in that decentralization in its fullest, consider hosting your own server or using some public server other than the largest/default one (`matrix.org`).

 There are 3 ways to get into Matrix, depending on your technical ability and needs:
 
-- **using the existing default server** - the easiest way is to use an existing server. The largest public Matrix server is `matrix.org` and it's configured as a default server in clients such as [Element Web](https://app.element.io) and many others. Just use Element Web on the browser via that link (or [download client apps for your Desktop or smartphone](https://element.io/app-for-productivity)), create an account and start chatting.

-- **using some other server** - instead of using the largest public server (`matrix.org`), you can use another public one. Here's a [list of public Matrix servers](https://joinmatrix.org/servers/) to choose from. Go to [Element Web](https://app.element.io) or download [some other client](https://matrix.org/clients/) of your choosing and adjust the homeserver URL during login.

-- **using your own server** - running your own server puts you in ultimate control of your data. It also lets you have your own user IDs (e.g. `@bob:example.com`). See [How do I set up my own Matrix server](#how-do-i-set-up-my-own-matrix-server).
