remap `gt` and `gT` doesn't work on markdown files

hi, currently i’m using <tab> and <s-tab> instead of gt and gT to switch between tabs. however these rebinding keys have no effect on markdown files

" use <tab> and <s-tab> to switch between tabs
nmap <tab> gt
nmap <s-tab> gT

pls note that gt and gT work as expected.

@Shatur95 nice catch

filetype is safe to use and can be useful to set per-type specific options/keys. Probably the markdown one, or some vim plugin overrides <tab>/<s-tab> bindings. Should be fixable by putting something like without disabling it:

autocmd FileType markdown nmap <tab> gt

See #115

Also few vim plugins require filetype to work, see #114

This option disables settings for specific file extensions. Most likely some plugin or your markdown settings were conflicting with this plugin. It is recommended to disable such stuff in VSCode.
