Removes more quotes on external command arguments (#13883)

Browse Source 
# Description
Fixes: #13662

I don't think nushell need to parse and keep nested quote on external
command arguments. Some nested quote is safe to removed. After the pr,
nushell will behave more likely to bash.

# User-Facing Changes
#### Before
```
> ^echo {a:1,b:'c',c:'d'}
{a:1,b:c',c:'d} 
```
#### After
```
> ^echo {a:1,b:'c',c:'d'}
{a:1,b:c,c:d}
```

# Tests + Formatting
Added some tests to cover the behavior
