chore(core): Deprecate tls1 and tls1.1

[neheb]

Both of these are deprecated.

[neheb]

The interesting thing on my Windows 8.1 machine is that TLS1.3 is available. So .Net 4.8 is installed?

[neheb]

Interestingly enough,

if (!($isNewerNetFramework -and $isSystemDefault)) {

evaluates to true on my machine. The weird thing is, [System.Net.ServicePointManager]::SecurityProtocol is set to SystemDefault. It shouldn't be evaluating to true and overwriting SystemDefault.

Please change base branch to develop instead of master.

[neheb]

Done.

I'm not familiar with TLS and .net, but for Win 7 and .net 4.5, should this cause errors?

And if we update minimal requirement to .net 4.7, this TLS sector could be removed IMO.

[neheb]

.net 4.5 supports tls 1.2. There's no change here other than removing 1.0 and 1.1.

I will say that even this is not enough to fix ScoopInstaller/Main#3593 . Maybe the issue needs to be reported to curl developers.

Update CHANGELOG please.

[neheb]

Done.
