fix(project.nvim): correctly delete projects (#4314)

## Description
Unfortunately, the upstream Github repo hasn't been active for over a
year. This overwrites the `history.delete_project` function to correctly
be able to delete projects. Because of `ipairs` being used, when you
delete the first key from the table the `for` loop iteration will just
stop, since there will be a gap between the available indices.
> will iterate over the pairs (`1,t[1]`), (`2,t[2]`), ..., up to the
first integer key absent from the table.

There's also a
[PR](https://github.com/ahmedkhalf/project.nvim/pull/106/files) for this
upstream, but like I mentioned the Github repo hasn't been active for
over a year.

Feel free to disregard, since this is obviously something that should be
rather fixed upstream under normal circumstances. I just created this
PR, since it's such a basic functionality with little change in
LazyVim's codebase, that I thought it might be acceptable.
