Before this patch, the “global” options passed to the Telescope command
were not passed down to the second prompt (the one selecting the files
for instance). This would cause a change of layout set like so:

```
:Telescope repo list layout_strategy=center
```

not to be applied to the second prompt.

This patch fixes that and correctly passes the options down to the
second prompt.

Related to #44 (might fix it)

fix: pass down the opts to the second prompts

Due to options being changed for the first picker (in particular, a
custom formatter is set), the second picker was unable to open any file,
it would only point to folders.

This commit fixes this behavior by passing down only the user options to
the second picker, along with the ones specifically needed by it.

Fixes #46

The old version is too different from my local one, causing the CI to
fail.

CI Update

Switch to an opened project directory, in each window and for the
corresponding file.

Fixes #8

The autocommand Lua API requires at least version 0.6. At the time of
writing, telescope requires nvim 0.7.

Add automatic cd to projecte directories

Some debian-based systems use put `bat` under `/usr/bin/batcat`. We thus
need a to look for `batcat` as well.

Fixes #47
