bug#75079: Default parser for treesit-explore

[Juri Linkov]

[-- Attachment #1: Type: text/plain, Size: 402 bytes --]

Currently loading the desktop is disrupted by the prompt
that asks for a parser name when treesit-explore-mode
was enabled in a buffer before.  The second part of the
following patch fixes this by omitting treesit-explore-mode.

But anyway it's very tedious to select the single parser
every time when enabling treesit-explore-mode.  So the
first part of this patch avoids this unnecessary selection:

That comment should explain _why_ we don't want desktop-save to save
this minor mode.  Otherwise it just says what the code does, which is
not hard to understand by looking at the code.

Thanks.
