Add ability to downrank some folders in the results (#350)

* add downrankedFoldersFilters to settings

* use downrankedFoldersFilters to downrank some files without excluding them in obsidian, which also prevents tags from being indexed

* change hotkey for toggling excerpts to ctrl-g

* change var to let for proper scoping

* trim folders after splitting them

* only log downranking when we actually do it

* format with Prettier

* make prompt-instruction-command still ctrl g for now
