errors when sorting and then changing NS

[mosheavni]

Describe the bug When sorting by age, then changing namespace, there are a lot of errors popping:

Error executing vim.schedule lua callback: /Users/mavni/Repos/kubectl.nvim/lua/kubectl/utils/marks.lua:60: Invalid 'col': out of range
stack traceback:
        [C]: in function 'nvim_buf_set_extmark'
        /Users/mavni/Repos/kubectl.nvim/lua/kubectl/utils/marks.lua:60: in function 'set_virtual_text_on_mark'
        /Users/mavni/Repos/kubectl.nvim/lua/kubectl/utils/marks.lua:50: in function 'set_sortby_header'
        ...mavni/Repos/kubectl.nvim/lua/kubectl/resourcebuilder.lua:317: in function <...mavni/Repos/kubectl.nvim/lua/kubectl/resourcebuilder.lua:316>

When sorting by name, an additional NAME column is added:

To Reproduce

1. Open fresh neovim window
2. Open Kubectl plugin
3. Sort by age
4. switch namespace
5. errors pop

Nice catch!

I messed up forgetting about the width shifting when filtering/changing namespace, it should be fixed now!
