fix: bump extendr and libR-sys to remove non-api calls warnings on R 4.5.0

[eitsupi]

Related to #1105

Since the new release of extendr contained some breaking changes that cannot be applied here (#1154, #1164, #1187), I cherry-picked only the relevant commits in the fork (rpolars/extendr#5).

Before:

* checking compiled code ... WARNING
Warning: File ‘polars/libs/polars.so’:
  Found non-API calls to R: ‘BODY’, ‘CLOENV’, ‘DATAPTR’, ‘ENCLOS’,
    ‘ENVFLAGS’, ‘FORMALS’, ‘FRAME’, ‘HASHTAB’, ‘PRCODE’, ‘PRENV’,
    ‘PRSEEN’, ‘PRVALUE’, ‘Rf_allocSExp’, ‘Rf_findVarInFrame3’,
    ‘SET_BODY’, ‘SET_CLOENV’, ‘SET_ENCLOS’, ‘SET_ENVFLAGS’,
    ‘SET_FORMALS’, ‘SET_PRCODE’, ‘SET_PRENV’, ‘SET_PRVALUE’,
    ‘STRING_PTR’, ‘SYMVALUE’, ‘XLENGTH_EX’
These entry points may be removed soon:
‘PRSEEN’, ‘SYMVALUE’

This PR:

* checking compiled code ... NOTE
File ‘polars/libs/polars.so’:
  Found non-API calls to R: ‘BODY’, ‘CLOENV’, ‘DATAPTR’, ‘ENCLOS’,
    ‘FORMALS’

My goal is to keep this package alive on the R-multiverse Production repository¹ after the R 4.5 release. (since I don't expect the next branch to replace this package in another month, related to #1336)

The WARNINGS seem to disappear with this change ( the current CI is probably too strict, as it does not turn green just because there is a NOTE)

LGTM, thanks I didn't think it would be that simple

Thank you.
I was disappointed that I couldn't delete the all NOTEs, but I gave up because I saw that the NOTE was also displayed in other extendr-based packages.

Anyway, I think this will support R 4.5.0.
