docs: Use tabs for examples on settings page (#8201)

* Split settings examples by type

Settings are split by the following where appropriate:

- meltano init
- meltano config
- export (environment variable)
- meltano command

* Remove settings file, renamed settings.mdx

* Move and rename tabs for consistency

* Update to enable "meltano config" to appear on one line in tab header

* Add fancy menu-color-active blue to selected tab

* Optional: Add queryString to shift all tabs as one

E.g. if you click on 'env' all tabs on the page shift to 'env' - helpful
if you have chosen one config style and want to stick to it for all
settings/config
