Fix use `[routerLink]` in `posts` and `series` - not click event

[samplelittlered]

• initially I have set the app to use [routerLink] but it got changed to on (click) event
• which is not only redundant for a elements but also causes the link to not be recognized properly in the browser and
• the context menu doesn't give the option of open link in a new tab

Describe the solution you'd like

• use [routerLink] a initially intend de in both series and posts

@samplelittlered @monacodelisa I was checking the code and well i changed the click of html and now it works perfectly, we have the option to open a new post in a new tab. I tested it and it is working perfectly, what do you think? or is there a scenario that is not being considered?

@jhonacs2 yes I think that was it, I assigned it to you, please apply it on the posts page and on the series page. And one more tiny thing since you are there - you see how there is a space before the comma on [post ,post.slug], please if you can make sure the space is after the comma like this [post, post.slug] in both places, thank you for lookin into it :)
