notes/obsidian-nvim: fix checkhealth by building from pin manually

As noted in comment, seems likely to be an issue related to setting
`src` differently, given the checkhealth was erroring on a null `commit`
retrieved by the script during the version check, although I didn't
debug extensively after fixing it.
