[FIX] odoo 15: declare xlsxwriter, which report_xlsx has always needed

The 15 bump died on

    Unable to upgrade module "report_xlsx" because an external
    dependency is not met: Python library not installed: xlsxwriter

report_xlsx declares {"python": ["xlsxwriter", "xlrd"]} and the 15
pyproject held xlrd alone: the pair arrived half. Every other version
from 12 to 18 declares it -- 15 was the only gap.

Version 1.4.5, as in 16 and 17, and well within what Python 3.8
supports. poetry lock --no-update touched exactly one package: nothing
else moved.

--- FR ---

Le palier 15 mourait sur « Python library not installed: xlsxwriter ».

report_xlsx déclare {"python": ["xlsxwriter", "xlrd"]} et le pyproject
de la 15 ne portait que xlrd : la paire est arrivée à moitié. Toutes les
autres versions de 12 à 18 le déclarent — la 15 était le seul trou.

Version 1.4.5, comme en 16 et 17, largement dans ce que Python 3.8
supporte. poetry lock --no-update n'a touché qu'un paquet : rien
d'autre n'a bougé.
