Fix/filter not filtering

[mosheavni]

fixes #308

[mosheavni]

it's because when we're on fallback view, the name is a table rather than a string (on defined views it's always a string):
https://github.com/mosheavni/kubectl.nvim/blob/8d664f366ef9afb3d842ffa3ec33805ba640d9f3/lua/kubectl/views/fallback/definition.lua#L73

then when we need to recuresively drop into name, it's using exact match which is almost never what we want, we want the pattern to be a substring of the field

Nice catch, do you have any idea why I couldn't replicate the bug??

I think if you search for a substring of some field in the fallback view, you wouldn't see it, only if it's exactly the same name
