Add dates to README.md table of versions

[Benjamin-Loison]

The dates are guessed from the dates of the posts linked in Version column.

The following commands can be used to ease reviewing this pull request:

sed -i 's/None | //g' README.md
sed -i 's/[0-9][0-9]\/[0-9][0-9]\/[0-9][0-9] | //' README.md

Note that I manually verified and corrected the chronological order and not repeated dates.

As a starting point I used the following algorithm:

from selenium import webdriver
from selenium.webdriver.firefox.options import Options
from lxml import html
import re
from datetime import datetime
import locale

# Necessary for parsing French dates.
locale.setlocale(locale.LC_TIME, 'fr_FR.utf8')

FILE_NAME = 'README.md'

with open(FILE_NAME) as f:
    lines = f.read().splitlines()

options = Options()
options.add_argument('-headless')
options.set_preference('permissions.default.image', 2)
browser = webdriver.Firefox(options=options)

#lines = lines[175:]

for lineIndex, line in enumerate(lines):
    #print(line)
    if line.startswith('| Version |'):
        line = f'| Date {line}'
    elif line.startswith('| - |'):
        line = f'| - {line}'
    elif line.startswith('| '):
        if 'Lounek' in line:
            continue
        match = re.search('\((http.*?)\)', line)
        print(lineIndex, line)
        tableDateStr = None
        try:
            url = match.groups()[0]
            print(url)
            if not 'http://www.dofus.com/?page=news&rubrique=v' in url:
                if not url.startswith('https://github.com/dofera/dofedex/releases/tag/'):
                    if match.span()[0] < line.index('|', 1):
                        entry = re.search('entry\d+', url)
                        #url = 'https://www.dofus.com/fr/forum/1751-dofus-retro/2396381-dofus-retro-mise-jour-1-41-reunification-dofus?page=1#entry13248306'

                        browser.get(url)

                        text = browser.page_source

                        tree = html.fromstring(text)

                        if entry is not None:
                            span = tree.xpath(f'//div[@id="{entry.group()}"]/div[2]/div[1]/div[1]/span[3]')
                            if span != []:
                                dateStr = span[0].attrib['title']
                                date = datetime.strptime(dateStr, '%d/%m/%Y - %H:%M:%S')
                            else:
                                # Should investigate this case.
                                date = None
                        else:
                            texts = list(tree.xpath('//span[@class="ak-subtitle"]')[0].itertext())
                            match len(texts):
                                case 2:
                                    dateStr = texts[1].lstrip()
                                    date = datetime.strptime(dateStr, '- %d/%m/%Y - %Hh%M')
                                case 3:
                                    dateStr = texts[2].strip()
                                    date = datetime.strptime(dateStr, '%d %B %Y - %H:%M:%S')
                                case 13:

There are 2 incorrect chronological ordered dates:

| 03/10/06 | 1.15.2 |
| 02/02/22 | 1.37.10 |

as other same day dates it is due to incorrect Version links.
