fix: correct misspellings (occurred, environments, separator/separated)

- packages/bruno-electron/src/app/collection-watcher.js: "occured" -> "occurred"
- packages/bruno-electron/src/ipc/preferences.js: "occured" -> "occurred", "environements" -> "environments"
- packages/bruno-app/.../CollectionItem/StyledWrapper.js: ".item-seperator" / ".seperator" -> ".item-separator" / ".separator" (no other refs to these CSS class names exist in the repo)
- packages/bruno-lang/v2/tests/list.spec.js: test description "list item are not seperated by atleast" -> "list items are not separated by at least" (29 tests still pass)
