Rewrite of spacy_install

[JBGruber]

Addresses #236. I use some newer functions from reticulate that were introduced since spacyr was developed. The installation process is now significantly easier (but there are also less options available for users). The default is to install spaCy in a virtual environment managed by reticulate (after checking if a suitable Python bin is available and installing it if not).

I tested it on two Linux machines (Arch and Debian) and Windows 10+11. On the Arch machine I also installed the GPU version. Apple silicone can also be used easily. The installation worked without hiccups (once C dependencies and reticulate were updated).

I assume that most people can now run spacy_install() without prior knowledge or any specific setup. But I still want to document how one could use a manual install by setting either SPACY_PYTHON or RETICULATE_PYTHON -- which should also be used as a troubleshooting guide. I think this should be a vignette rather than the landing page of https://spacyr.quanteda.io (but that might be a different PR).

Let me know what you think 😁

I changed the installation.rmd. Now all that is left is to adapt the tests.

Unfortunatly, it seems that remove_symbols does not work correctly anymore:

library(spacyr)
txt <- "This: £ = GBP! 15% not! > 20 percent?"
spacy_tokenize(txt, remove_symbols = TRUE, padding = FALSE)
#> successfully initialized (spaCy Version: 3.6.1, language model: en_core_web_sm)
#> $text1
#>  [1] "This"    ":"       "="       "GBP"     "!"       "15"      "%"      
[8] "not"     "!"       ">"       "20"      "percent" "?"

^{Created on 2023-08-31 with reprex v2.0.2}

This is due to an upstream change in spaCy though.

import spacy
doc = nlp("This: £ = GBP! 15% not! > 20 percent?")

for t in doc:
    print(t, t.pos_)
>>>  This PRON
>>>  : PUNCT
>>>  £ PROPN
>>>  = X
>>>  GBP PROPN
>>>  ! PROPN
>>>  15 NUM
>>>  % NOUN
>>>  not PART
>>>  ! PUNCT
>>>  > X
>>>  20 NUM
>>>  percent NOUN
>>>  ? PUNCT

To test if something is a symbol, you use w.pos_ == "SYM", which does not work anymore since = is now classified as X for some reason. I remove the test.

There are a few more inconsitencies that lead to failing tests. Where I think those have nothing to do with this PR, but instead are upstream changes, I skip them with skip("behaviour changed in spaCy"). Otherwise tests succeed (at least on my machine) now.

This is really welcome @JBGruber. Sorry it took me so long to get to it. I incremented the verson to 1.3. It's full of breaking changes but only to spacy_install(). So be it.
