[Keymap] Ergodash keymap for yet-another-developer (#7046)

* Initialize ergodash rev 1 keymap

./util/new_keymap.sh ergodash/rev1 yet-another-developer

* Add user space configurations referenced from drashna

* Start community layout for ergodash in ortho_5x14

* Remove unused layers

* Add userspace layers

* Add Userspace gitignore

Hide Secrets

* Remove userspace unused drashna features

* Scrap default keymap and follow drashna's template

* Add code referenced from kuchosauronad0

* Make sure that the author is named Developer

* Replace middle keys del and bksp with curly brace

* Reduce ONESHOT_TIMEOUT from 3sec to 2sec

* Remove adjust key AG_SWAP

* Disable UNICODEMAP_ENABLE, remove code causing build fail

* Increase TAPPING_TERM to 240

Reason:  Because Space is also LOWER, space sometimes not registering.
PS: I dont want to #define RETRO_TAPPING yet

* Update KC_MAKE to use :flash

* Remove TAP_ONCE, use tap_code
