chore: Fix algokit goal links

[iglosiggio]

During a migration we some links changed. This PR fixes them.

Some stuff is still to be fixed, mainly because it should point at the goal clerk docs but we don't have them on our devportal.

Remaining errors (for this specific link) on this repo:

$ git grep "https://dev.algorand.co/algokit/algokit-cli/goal"
