security_engines/dashboard next button points ot dashboard too

[rr404]

When on this page ...

https://docs.crowdsec.net/u/console/security_engines/dashboard

... the next page, at the bottom, is also "dashboard", so we are in a loop

Seems it does that with all pages having sub sections and a default main page. Alerts does that too

This issue exists for all pages in console docs that use another page as the same page as the dropdown button. The fix is defining within the toml header the next and previous buttons.

Example:

crowdsec-docs/crowdsec-docs/unversioned/getting_started/installation/pfsense.mdx

Lines 4 to 5 in a2db31d

	pagination_prev: getting_started/pre_requisites
	pagination_next: getting_started/next_steps

(you have to define both next and prev you cant just define one option)
